All accept the same auth flags: +`-E` (Windows), `-A` (Entra), `-T ` (access token), `-U/-P` (SQL +auth). + +## Working rules (apply to ALL tools in this repo) + +### 1. Stay in the tool's folder +Each tool is independently buildable and publishable. When the user asks +to build, test, or run a tool, `cd` into that tool's folder first and use +**its own** `build.ps1`, `smoke-test.ps1`, `full-test-suite.ps1`, and +`publish.ps1`. Do not invoke `cmake`, `msbuild`, `python -m build`, or +ad-hoc compile commands directly. + +### 2. Check the terminal context before running anything +Before running any build / test / `*.exe` command, inspect the current +terminal's `Last Command:` and `Exit Code:`. If the user already ran it +successfully, ask about the result instead of re-running. + +### 3. No shell redirects in tool invocations +Do not append `2>&1`, `> file`, or `| Select-String` to tool commands. The +terminal already captures both streams, and filtering hides diagnostic +output. If you need to inspect output, capture it into a PowerShell +variable: `$out = .\build\Release\sqlsim.exe ...`. + +### 4. JSON output is canonical +Each tool supports `-json` (or `--json`). Results files are JSON — parse +with `ConvertFrom-Json`, never by hand. When comparing runs, compute +deltas between phases, never cumulative values. + +### 5. Authentication is required, every time +No tool defaults to an auth mode. Every command must include one of: +`-E`, `-A`, `-T `, `-U -P `, or +`-c ""` (where supported). For Azure SQL, prefer `-T` with a +token obtained via `az account get-access-token` to avoid interactive +popups on repeated runs. + +### 6. Don't "improve" working code from memory +If a `SKILL.md`, a tool's `AGENTS.md` or `.github/copilot-instructions.md`, +or an existing working `.sql` / `.ps1` demonstrates a syntax, mirror it +exactly. Verify unfamiliar T-SQL / driver syntax against Microsoft Learn +before writing. + +## Release / publish workflow + +The authoritative release pipeline is `.github/workflows/release.yml` — +triggered by pushing a `v*.*.*` tag or manually via `workflow_dispatch` for RC +validation. Both paths build and validate every public asset. Manual dispatches +retain GitHub Actions artifacts only and cannot create a tag or release. Tag +pushes additionally attach the assets to a draft GitHub Release. sqlsim and +sqlpysim each ship as their own asset. sqlsim Studio ships only in +`sqlsimtools--win-x64.zip`, which `release/build-sqlsimtools-bundle.ps1` +assembles from the unchanged sqlsim x64 and sqlpysim archives plus Studio in +`sqlsimstudio/`. + +**Nothing else triggers a release.** Routine commits, PR merges, and the +passage of time do not produce ZIPs. Publish cadence is fully manual. + +```powershell +# Real release: tag and push. Workflow fires automatically. +git checkout main; git pull +git tag v1.0.1 +git push origin v1.0.1 +# Then click "Publish" in the GitHub Releases UI. + +# RC validation: build Actions artifacts without creating a tag or release. +gh workflow run release.yml --repo microsoft/sqlsimtools --ref main ` + -f version=1.0.1-rc1 +# Download and inspect the artifacts from the completed workflow run. +``` + +For ad-hoc local builds, `release/publish.ps1 -PublishAll` calls each +tool's own `publish.ps1` in sequence. Each tool stages its output under +its own folder; nothing is assembled at the root. + +```powershell +# Local build of every tool (optional) +cd release; .\publish.ps1 -PublishAll + +# Same, reusing existing binaries +cd release; .\publish.ps1 -PublishAll -SkipBuild +``` + +Individual tools also have their own `publish.ps1` for tool-only +releases. + +## Branching & versioning (post-v1.0.0) + +Default branch is `main` — it always reflects the latest released code. +Don't commit directly to it. + +**Per-change flow:** + +1.

Don't bundle unrelated work. +2. Open PR ` → main`. `sqlsim CI` runs automatically; PR cannot merge until green. +3. Merge to `main`. Squash-merge for small fixes; merge-commit when multiple commits are worth preserving. +4.

The Release workflow's + `verify-version` job fails when any of them differs from the tag; check with + `./release/check-release-version.ps1 -Version v`. + +5. `git push origin v` → Release workflow fires → click **Publish** in the UI. + +**Before tagging real:** always do a `workflow_dispatch` dry run with +`-f version=-rc1`, download and inspect the Actions artifacts, then tag +for real.

The file is replaced atomically, so it is safe to poll.

Certificate validation follows `sqlcmd` (Go): neither `-N` nor `-C` means the certificate is not validated, `-N` without `-C` requires validation, and `-C` bypasses it. This applies to every authentication mode including `-T`. For Azure SQL prefer `-N m`; use `-C` only for a self-signed server, or `-F ` when the connected name differs from the certificate name. +9.

Do not rerun a successful current-artifact step. +3. Never print, log, or screenshot bootstrap URLs, tokens, or passwords. Let + Studio open the browser, or launch with `--no-open --bootstrap-file ` + and tell the user to use the window that opens. +4. The bootstrap token is single-use and its file is deleted after the first + visit. A second visit, a stale tab, or a tab on a different port returns 404 + with a blank page. That is the auth gate, not a broken build. Relaunch for a + fresh URL rather than debugging the 404. +5. Studio's client assets are embedded resources. If `client/*` changed, + `build.ps1` must run before the change is visible. +6. `smoke-test.ps1 -SkipBuild` runs a stale non-RID DLL from + `server/bin/Release/net10.0/`. Always pass + `-StudioExecutable .\build\win-x64\sqlsimstudio.exe` or omit `-SkipBuild`. +7. Present one run at a time. Do not paste the whole matrix into chat. +8. Never mark a run Pass for the user. Report what you observe from the API if + asked, but the user decides the outcome. +9. Treat a cancelled run as `Stopped`, not a failure. Cancelling is supported + and Studio reports it as such. +10. Do not quote absolute durations as pass criteria. See Measurement Honesty. + +## Preflight + +Run once per session, before the first test. + +1. Confirm AdventureWorksLT is reachable and populated: + + ```powershell + .\build\win-x64\sqlsim\sqlsim.exe ` + -S -d AdventureWorksLT -E -C ` + -Q "SELECT COUNT(*) AS Customers FROM SalesLT.Customer" + ``` + + 847 is the expected count. A different number means a partial or non-standard + restore; report it rather than proceeding silently. Do not add `-q`: it + suppresses result rows, which is the value this check reads. + +2. Confirm a Studio package exists at `build\win-x64\sqlsimstudio.exe`. If not, + run `.\build.ps1 -Runtime win-x64`. That build requires a matching sqlsim + binary at `..\sqlsim\build\x64\Release\sqlsim.exe` and fails without it, so + build sqlsim first with `..\sqlsim\build.ps1 -Architecture x64`. + +3. Launch Studio and confirm the listener before handing over to the user. + +4. For Azure targets, confirm the auth mode with the user before the first run. + Prefer a token obtained outside chat over interactive sign-in, which prompts + on every run. + +## Per-Run Chat Protocol + +Use this exact compact shape: + +```markdown +**MEDIUM - Query mode** + +Configure tab: + +1.

Connections (-n) **4**, Iterations per connection (-r) **3**. +4. Client telemetry **Live progress**. +5. Studio server statistics **Runtime messages**. +6. Run workload, then switch to the Monitor tab. + +Watch for: several progress ticks per execution, a non-zero execution rate once +the first execution completes, and a measured average duration. +``` + +Then ask one outcome question with the questions tool offering Pass, Fail, +Stopped, and Skip, allowing a free-form observation. After the answer, record it +and present the next run. + +## What Each Tier Is For + +State the purpose when presenting a tier, so the user knows what to watch. + +- **Light**: reachability, the Results page, and fast iteration. Deliberately + too fast for live monitoring to show anything, because sqlsim counts an + execution only on completion, so a sub-second query reports zero throughput + for its whole duration. If the user wants to watch the Monitor work, move to + medium. +- **Medium**: live monitoring. Executions span several one-second progress + ticks, so the rate, the progress bars, and the measured average duration all + have something to show. +- **Heavy**: cancellation, query timeout, sustained load, and connection + pressure. + +## Before Any Heavy Run + +Raise the **Query timeout** above its 30 second default first. A heavy execution +can exceed 30 seconds under concurrency and the run will fail with a timeout, +which is a valid test but not this one. + +On Azure SQL Database, halve every connection count. On a small service tier the +heavy tier measures throttling rather than client behavior. Say this before the +run, not after it fails. + +## Measurement Honesty + +1. Durations in the assets were measured on one hybrid-core laptop against a + warm cache. They are relative, not thresholds. Never fail a run for missing a + quoted number. +2. On hybrid-core hosts, identical runs land in two clusters more than 2x apart + depending on core scheduling. Take a median of several runs before treating a + timing change as real. +3. A cold cache roughly doubles the first execution. Discard the first run of a + tier when comparing. +4. Studio's Results page reports query time as the sum across connections, so a + ten-connection run shows roughly ten times the wall clock. Use the measured + average duration instead. +5. Before trusting any timing, confirm the server is healthy. Buffer pool + pressure or error 802 in the SQL error log invalidates every measurement, and + the symptom is slow runs rather than an obvious failure. + +## Known Behavior, Not Defects + +Do not let the user record these as failures. + +- A live-telemetry run has no final results JSON. Studio sources the Results + page from periodic query-statistics snapshots instead, and shows `--` where a + value genuinely was not measured. +- Stopping a run reports `Stopped`, not `Failed`. +- With Studio server statistics set to **None**, a failed live run has no SQL + error text available anywhere, only an exit code. Re-run with **Runtime + messages** to get the message. +- Workload groups that reference a script by file path are skipped on import + with a toast, because Studio cannot read a path from the browser.

Create the session report with all test IDs initially `Pending`. +6. Stop any running Studio instance before rebuilding. +7.

Do not ask the user to answer several tests at +once. After the answer: + +1. Write the status and observation to the report. +2. If Pass, present the next test. +3. If Fail, ask only for the missing non-secret observation/evidence needed to + diagnose, then fix or record the defect before proceeding. +4. If Blocked, record the blocker and offer the exact unblock action. +5. If Skip, record a concrete reason. + +At the end of each section, report only the delta: + +```text +Section 3 complete: 7 passed, 0 failed. Overall: 16/ complete.

Studio +runs the bundled engines from `../sqlsim/x64` and `../sqlpysim`, so the bundle +carries no second copy of either: + +```text +README.md +.github/skills/{sqlsim,sqlpysim,sqlsimstudio}/SKILL.md +.github/agents/sqlsimtools-workload-builder.agent.md +sqlsim/... the complete sqlsim win-x64 archive +sqlpysim/... the complete sqlpysim archive +sqlsimstudio/sqlsimstudio.exe +sqlsimstudio/sqlsimstudio.md +sqlsimstudio/sqlsimstudio.html +sqlsimstudio/CONFIGURATION.md +sqlsimstudio/sqlsimstudio-cleanup.ps1 +sqlsimstudio/examples/ +sqlsimstudio/LICENSE +sqlsimstudio/THIRD-PARTY-NOTICES.md +``` + +The bundle script refuses differing overlapping files, an ARM64 sqlsim payload, +and missing entry points. The `build-sqlsimtools` job then validates the bundle +with `validate-package-layout.ps1` for both tools, the Studio startup smoke +test, and the Studio offline suite, which proves Studio finds the bundled +sqlsim. The Private Preview Linux Studio artifact remains a standalone Studio +build with its own engine copies: + +```text +sqlsimstudio +sqlsim/sqlsim +sqlpysim/sqlpysim.py +sqlpysim/requirements.txt +.github/skills/sqlsimstudio/SKILL.md +sqlsimstudio.md +CONFIGURATION.md +examples/ +LICENSE +THIRD-PARTY-NOTICES.md +``` + +Studio also ships native libraries beside the executable. `PublishSingleFile` +bundles managed assemblies only; the operating system loader requires native +libraries on disk. Do not treat `icudt72.dll`, `icuin72.dll`, `icuuc72.dll`, or +`Microsoft.Data.SqlClient.SNI.dll` as packaging defects. App-local ICU is +pinned deliberately so string comparison and sorting stay identical across +machines. + +## Parity rule + +Four publish paths stage the same logical layout and drift independently: + +- `sqlsim/publish.ps1` +- `sqlsim/publish-linux.sh` +- `sqlpysim/publish.ps1` +- `sqlsimstudio/build.ps1` and `sqlsimstudio/build-linux.sh` +- `release/build-sqlsimtools-bundle.ps1` + +When adding or renaming any staged file, update every affected script in the +same change, then add the path to `release/validate-package-layout.ps1` or to +the sqlsimtools and Linux Studio checks in `.github/workflows/release.yml`. A file that only one +platform stages is a defect that reaches users as a missing license, a missing +agent file, or a failed release job. + +The sqlsim and sqlpysim publishers also install into existing projects, so +they must never delete project files or silently replace one that differs. +`sqlsim/publish.ps1` and `sqlpysim/publish.ps1` share +`release/OverlayInstall.psm1` for this; `sqlsim/publish-linux.sh` implements +the same rules. Keep `release/test-overlay-install.ps1` and +`release/test-overlay-install-linux.sh` passing; sqlsim CI runs both. + +## Workflow triggers + +`.github/workflows/release.yml` runs two ways. + +| Trigger | Result | +|---------|--------| +| `workflow_dispatch` with a version input | Builds and validates every asset, uploads GitHub Actions artifacts only. No tag, no Release. | +| Push a tag matching `v*.*.*` | Builds everything and creates a draft GitHub Release for review. | + +Only the tag path has `contents: write`. Manual runs cannot publish. + +The workflow does not modify in-tree version constants. Its first job, +`verify-version`, runs `release/check-release-version.ps1` and fails the run +unless the tag or RC label (ignoring a `v` prefix and any `-rc` suffix) matches +the version in every one of these files: + +- `sqlsim/include/version.h` (`SQLSIM_VERSION`) +- `sqlsim/CMakeLists.txt` (`project(sqlsim VERSION ...)`) +- `sqlpysim/sqlpysim.py` (`__version__`) +- `sqlpysim/setup.py` (`version=`) +- `sqlsimstudio/server/SqlsimStudio.csproj` (``) + +Bump all five in the release PR, then confirm locally before tagging: + +```powershell +./release/check-release-version.ps1 -Version v1.0.1 +``` + +## Release candidate dry run + +Always dry run before tagging. + +```powershell +gh workflow run release.yml --ref main -f version=1.0.0-rc1 +gh run list --workflow=release.yml --limit 1 +gh run watch +``` + +Download and inspect the artifacts: + +```powershell +gh run download --dir ./rc-artifacts +``` + +For each archive, extract to an empty directory and confirm: + +- The overlay paths above exist, with no extra wrapper directory. +- `sqlsim --version` and `sqlsim -h` run from the extracted copy. +- `LICENSE` and `THIRD-PARTY-NOTICES.md` are present in every archive. +- The workload-builder agent is present in both sqlsim and sqlpysim archives. + +The workflow already extracts each archive and runs +`release/validate-package-layout.ps1` against it, runs the Studio smoke test +and offline suite against the sqlsimtools bundle, and smoke tests the Private +Preview Linux Studio build. A green run means layout and startup +passed; it does not mean the tools were exercised against a live SQL target. + +## Publish a version + +Use semantic versioning: patch for a fix, minor for a compatible feature, +major for a breaking CLI or output change. + +```powershell +git checkout main +git pull +git tag v1.0.0 +git push origin v1.0.0 +``` + +The tag starts the workflow and creates a draft Release with generated notes. +Review the draft and its assets, then publish it in the Releases UI. + +Do not move a published tag, replace assets on an existing release, or delete +older releases. Ship a new patch version instead. + +## Local builds + +`release/publish.ps1 -PublishAll` runs each tool's publish script in sequence +and stages output under `release/sqlsimtools/1.0/`. That directory is ignored +by Git, is not the release pipeline, and can be stale. Never use it to judge +what an archive contains. Use artifacts from a dry run instead. + +## Rules + +1. Never tag without a passing dry run on the same commit. +2. Never edit one publish script without checking the other three. +3. Every archive ships `LICENSE` and `THIRD-PARTY-NOTICES.md`. +4. Parse JSON with a structured parser. Do not append `2>&1` or pipe tool + output through text filters when capturing results. +5. Treat a validation failure as a packaging defect, not a flaky run. diff --git a/.github/workflows/driver-update-monitor.yml b/.github/workflows/driver-update-monitor.yml new file mode 100644 index 0000000..c9ad7b1 --- /dev/null +++ b/.github/workflows/driver-update-monitor.yml @@ -0,0 +1,243 @@ +name: Driver update monitor + +on: + schedule: + -

To propose work or follow a +specific item, open a +[GitHub issue](https://github.com/microsoft/sqlsimtools/issues) or start a +[discussion](https://github.com/microsoft/sqlsimtools/discussions). + +## Release status + +| Component | Public availability | Preview status | +| --- | --- | --- | +| `sqlsim` | Windows x64, Windows ARM64, and Ubuntu x64 | Public Preview. | +| `sqlpysim` | Source distribution validated on Windows x64 and Ubuntu 24.04 and 26.04 LTS x64 | Public Preview; compatibility work continues. | +| `sqlsim Studio` | v1.0 Public Preview on Windows x64 | Ubuntu x64, Windows ARM64, and macOS ARM64 are in invitation-only Private Preview pending platform validation; macOS also requires signing and notarization decisions. | + +Platform support targets SQL Server 2019, 2022, and 2025, Azure SQL Database, +Azure SQL Managed Instance, and SQL database in Microsoft Fabric. + +## Open + +### Testing and validation + +- **Close the sqlpysim workload and live-telemetry gaps.** Agreed as the next + piece of work, in this order, because the three share plumbing and together + restore what Studio currently disables for the Python engine: + 1. ~~`-workload` for mixed workload groups, per-group threads, think time and + duration mode.~~ Implemented, and enabled in Studio. sqlpysim parses the + same file format with the same validation and wording, expands groups + into per-thread assignments, and reports the same text header and JSON + `workloads` array. Studio now accepts `mode=workload` for the Python + engine and leaves the Workload tab selectable. Covered by ten tests in + sqlpysim's suite, eight scenarios in + [scripts/check-engine-parity.ps1](scripts/check-engine-parity.ps1), and + Studio's own suites. + 2. ~~`-stream-json` for the `started`, `progress` and `completed` events.~~ + Implemented, and enabled in Studio. sqlpysim emits the same three event + types with the same field names and ordering, on the same one-second + tick, with cumulative counters and a running-average throughput. It + implies JSON mode. Both engines accept + `-stream-json -json -o ` to preserve canonical final results while + streaming. Studio accepts live telemetry for the Python engine and + leaves the option selectable. Covered by four tests in sqlpysim's smoke + suite, ten in its full suite, five scenarios in + [scripts/check-engine-parity.ps1](scripts/check-engine-parity.ps1), and + Studio's API and GUI suites. + 3. ~~`-querystats-interval` and `-querystats-file` for periodic query-stat + snapshots.~~ Implemented, and enabled in Studio. sqlpysim writes the same + snapshot shape with the same nested blocks and field names, on the same + cadence, replacing the file atomically so a reader never sees a partial + write. The interval implies `-querystats`, defaults its file to + `querystats-live.json`, and swallows write failures, all matching sqlsim. + Studio now accepts runtime statistics for the Python engine. Covered by + four tests in sqlpysim's smoke suite, ten in its full suite, five + scenarios in + [scripts/check-engine-parity.ps1](scripts/check-engine-parity.ps1), and + Studio's API and GUI suites. +- **Investigate the remaining sqlpysim differences before deciding on them.** + Deliberately pending. The list below separates what has been measured from + what is only claimed in [RELEASE-NOTES.md](RELEASE-NOTES.md), because the two + have not been distinguished before and reasoning about this surface has + proved unreliable: of two hypotheses formed and then tested in September + 2026, one was confirmed and one refuted. + - *Verified.* `-p` warns and runs unprepared. `-app` is rejected because + `mssql-python` reserves the application name and always reports + `MSSQL-Python`; Studio disables the field for sqlpysim. `-F` is not exposed + in v1.0; support will be investigated for a future release. `-replay` and + `-replayfile` are deliberately deferred from the v1.0 Public Preview; + future support may be considered, while `sqlsim` remains the supported + replay engine. Documented in + [sqlpysim/sqlpysim.md](sqlpysim/sqlpysim.md). + - *Claimed, unverified.* Nothing outstanding: JSON field names and supported + configuration/operation shapes now match, both tools time execution through + result consumption, both report zero fetch operations in JSON mode, and + both use `SET STATISTICS TIME/IO` for `-querystats`. + - *Needs measurement rather than engineering.* Nothing outstanding: Studio's + block on `statisticsSource=runtime` for sqlpysim was the last item here, + and it has been lifted now that `-querystats-interval` and + `-querystats-file` are implemented and compared against sqlsim. + - *Likely permanent rather than pending.* `-p` cannot reproduce sqlsim's + prepare/execute mode for complete SQL text because `mssql-python` prepares + only executions with bound parameters, and sqlpysim has no + parameter-binding input. `-app` is reserved by `mssql-python`. Listing + these beside fixable gaps makes the surface look larger and vaguer than it + is. +- **Make sqlpysim as compatible with sqlsim as the driver permits.** Close the + CLI, behavior, and output gaps cataloged in + [RELEASE-NOTES.md](RELEASE-NOTES.md). + [scripts/check-engine-parity.ps1](scripts/check-engine-parity.ps1) runs the + same arguments through both engines and compares structure rather than text, + so a difference has to be either fixed or declared. Extend its scenarios as + coverage grows: it currently exercises single and concurrent execution, GO + batches, failures, and output modes, and does not yet cover `-i` file input, + reconnect, retry, encryption levels, authentication modes, or the JSON + schema. Any difference imposed by `mssql-python` should remain explicit and + tested rather than hidden behind a general compatibility claim. +- **Extend live driver validation across platforms and authentication modes.** + [DRIVER-COMPATIBILITY.md](DRIVER-COMPATIBILITY.md) records only combinations + that have been proven. Remaining gaps include access-token and SQL + authentication for `sqlpysim` on Windows; Azure SQL access-token + authentication for `sqlsim` on Linux; managed-identity and service-principal + authentication on Linux for both tools; and Kerberos (`-E`) on Linux, which + requires a domain-joined host. Unvalidated combinations remain documented as + unverified rather than supported. +- **Close the remaining Linux test-harness portability gaps.** The first full + Linux run of both suites showed that the remaining failures are harness + defects rather than product defects. Outstanding items: test cases that + hard-code `-E` instead of the suite's configured authentication, fixtures + that use Windows path separators, a harness that merges standard error into + standard output before parsing JSON, assertions that match Windows-specific + TLS error wording, and output-file permission tests written against Windows + ACL semantics. +- **Guard PowerShell and bash test-suite parity.** The project deliberately + maintains separate PowerShell and bash suites so Linux users never need + PowerShell, which makes drift the primary risk. Each suite should declare its + test inventory as data so a check can fail when the two diverge. + [scripts/check-suite-parity.ps1](scripts/check-suite-parity.ps1) is the + starting point. +- **Automate the smoke and full test suites on hosted runners.** Ubuntu runners + can start SQL Server in a container as a live target. Windows runners include + no SQL Server engine, so a live Windows job requires installing Developer + Edition during the run. Azure-specific authentication coverage would stay on + manual dispatch because it needs federated credentials and a firewall + allowance. +- **Extend the tiered AdventureWorksLT load tests to sqlpysim.** + [sqlsimstudio/examples/adventureworkslt](sqlsimstudio/examples/adventureworkslt) + and the `sqlsimstudio-load-test` skill cover light, medium, and heavy runs in + Query, SQL file, and Workload modes, but only against the sqlsim engine. Add + the equivalent coverage for sqlpysim, limited to what that engine actually + supports: Studio disables Replay mode and the runtime-statistics option when + the Python engine is selected, so the matrix reduces to Query, SQL file and + Workload modes with live progress or final results. The SQL assets themselves are engine-neutral and should be reused rather + than duplicated. Expect different tier boundaries: the Python client's + per-iteration overhead is higher, so the light tier's connection and iteration + counts may need lowering to keep the run dominated by server work. Revisit the + excluded modes as the parity work above lands. + +- **Fix the race in the Studio GUI cancellation step.** + `gui-tests/studio.spec.cjs` fails intermittently on a loaded machine. The + trace shows a single `DELETE /api/runs/current` returning 404 at the step + that starts a ten second `WAITFOR` and clicks Stop run. A `DELETE` with + nothing running correctly returns 404, and Studio's own suite asserts that, + so the 404 is the server behaving properly. The test then fails because it + asserts the browser console is entirely clean, and a 404 is logged there + even though `fetch` resolves normally and the client catch never fires. + Under load the click can land after the run has already ended, so the stop + finds nothing to stop. The fix is for the cancellation step to tolerate a + run that finished before the click, rather than requiring a console with no + entries at all. Not caused by the sqlpysim workload work: the failing step + never selects sqlpysim and never touches workload mode. Whether it predates + the shutdown changes in `daa4704` is still unestablished; an earlier attempt + to reproduce it on a clean checkout stashed only the Studio files, so those + changes were still present in the build under test. + +### Tooling and platform coverage + +- **Provide a bash equivalent of `replay/convert-xel.ps1`.** Linux users cannot + currently capture a trace for replay without PowerShell. +- **Complete macOS ARM64 validation and decide its release path.** The native + Apple Silicon build, offline smoke tests, and packaging already succeed in + CI. Promotion to Public Preview depends on live validation against a real SQL + target on Apple Silicon and a decision on signing and notarization. +- **Publish release asset checksums.** Generating a `SHA256SUMS` file as part of + the release workflow would let users verify downloads. +- **Offer HTML reporting from sqlsim Studio.** Studio exports the canonical + `-json` results file and a comparison bundle, which are exactly the inputs + [`execution-report.ps1`](sqlsim/examples/reports/execution-report.ps1) and + [`comparison-report.ps1`](sqlsim/examples/reports/comparison-report.ps1) + consume, and the sqlsimtools package ships those scripts in `sqlsim/` beside + Studio. Reports are still a two-step flow: export, then run the script. A + future revision should generate both reports directly from the Results and + Compare views, reusing the shipped generators rather than reimplementing + them in the browser. +- **Seed the replay database context from the connection.** `currentDatabase_` + in [odbc_connection.cpp](sqlsim/src/odbc_connection.cpp) starts empty and is + only assigned after a successful `USE`, so replay issues `USE [database]` on + the first event that names one even when the connection is already in that + database. Initializing it from the connect-time database would make that + redundant statement disappear, which matters for Azure SQL Database and SQL + database in Microsoft Fabric: neither supports `USE` for switching databases, + so today a single-database capture replayed into its own database still runs + a statement that fails and is silently tolerated. Faithful switching for + genuinely multi-database captures must keep working; + `sqlsim/testing/clean-replay.xml` alternates between `master` and `tempdb` and + is the fixture that covers it. + +### Remaining sqlsim Studio control gaps + +- **Add source-to-target database mapping for multi-database Replay.** Studio + v1.0 accepts captures with zero or one database. A single captured database + is redirected automatically to the database selected in Configure, while a + capture containing multiple distinct databases is rejected during preflight. + A future mapping UI should list every captured source database, prefill each + destination with the same name, allow overrides, validate every destination, + and stage private Replay XML with those mappings. Studio must continue to + state that connectivity validation does not prove schema or data equivalence. + +- **Make Studio able to run a real sqlsim workload file.** Found while + preparing an Azure SQL Hyperscale demo from + `azuresqlfoundations/scale/scale-workload-baseline.json`, a 250-connection, + six-group, 120-second workload that Studio refused outright. Three separate + gaps, in the order a user meets them: + 1. **Groups that reference SQL by path cannot be imported.** sqlsim's own + format is `{ "file": "queries/loan-eligibility.sql", ... }`, but Import + JSON runs in the browser, which can read only the file chosen in the + picker. Every file-backed group is skipped, and a file where all groups + are file-backed fails with "No groups contained inline queries". This is + the shape real workloads are written in, so Studio currently cannot open + most of them. A server-side import endpoint could resolve paths relative + to the uploaded file; a file-picker for the referenced scripts is a weaker + alternative. + 2. **`duration_seconds` is ignored and silently becomes one iteration.** + Studio notes that it ignored the key, but a duration-mode file has no + `iterations`, and Studio defaults a missing count to 1 — so a workload + meant to run for two minutes runs each thread once and ends in seconds. + Either implement duration mode or refuse the file rather than running + something unrecognisably smaller. + 3. **`ramp_batch_size` and `ramp_delay_ms` are dropped without comment.** + Every connection opens at once instead of in staged batches. For 250 + connections against Azure SQL that is a login storm and a materially + different test. At minimum say so on import, as is done for + `duration_seconds`. + + [sqlsimstudio/examples/convert-workload-for-studio.ps1](sqlsimstudio/examples/convert-workload-for-studio.ps1) + works around the first gap by inlining the referenced scripts, and reports + the other two. It is a stopgap: the conversion is lossy, because duration and + ramp-up cannot be expressed in what Studio accepts. + +- **Add a Get token button beside the Entra token field.** Today the user + leaves Studio, runs + `az account get-access-token --resource https://database.windows.net --query accessToken -o tsv` + in a terminal, and pastes a 2,600-character string back into the browser. + Measured during an Azure SQL Hyperscale demo, that round trip went wrong + twice in one session: the clipboard was overwritten by an unrelated copy + before it reached the field, and an earlier attempt returned a cached token + with eleven minutes left, because `az` only refreshes within five minutes of + expiry. A button that shells out to `az account get-access-token` and fills + the field removes both failure modes. + + Requirements, mostly security: + - The token must never reach a log, the execution log display, the command + preview, or an exported result. It is a bearer credential with the same + weight as a password, and the existing field is already masked. + - Fail clearly when `az` is absent or signed out, naming the command to run, + rather than surfacing a raw CLI error. + - Offer a tenant override. `az` defaults to the signed-in tenant, which is + not necessarily the one hosting the target server. + - Show the expiry time once filled, and warn below roughly ten minutes. An + access token is presented per connection at connect time, so a run that + starts before expiry completes normally; the trap is a second run started + afterwards. + - Keep manual paste working. A user with a token from elsewhere, or on a + host without `az`, must not be forced through the button. + +- **Validate Entra interactive, managed identity, and service principal against + live targets.** All three are wired and their credential rules are enforced, + but automated coverage stops at request validation. Managed identity needs an + Azure host to exercise, and interactive needs a human at a sign-in prompt. +- **Restore the convenience actions removed for v1.0.** These were taken out of + the interface rather than shipped disabled, and should return once + implemented: + - Copy the Monitor event stream to the clipboard + - Run again, from the Results view + - Open a completed run's configuration back in the Configure view + - Copy, export, and clear the execution log display +- **Expose `-c` (raw connection string) and `-v` (verbose) as user-facing + options.** Studio passes `-v` for final-results runs so exported JSON matches + the reporting script's input, but neither flag is selectable in the interface. +- **Carry error text on the `-stream-json` progress event.** The stream reports + an error *count* and a terminal `"status":"error"`, but never the message, and + a failing run writes nothing to stderr. Verified with a syntax error: stderr + empty, the completed event carried `failed_executions:1, errors:1`, and the + only copy of `Incorrect syntax near '*'` was in the querystats snapshot. + Studio now promotes that snapshot's `recent_errors`, so live runs with + Runtime messages show the failing query and message, but a live run with + statistics set to None still has no channel carrying a reason. Adding an + `errors` array to the progress or completed event would close this for every + live run without forcing `SET STATISTICS` overhead. +- **Design a proper results view for live-telemetry runs.** `-stream-json` + never emits the final aggregate metrics block: a run with `-o` writes only + the progress events to that file, so `metrics`, `avg_elapsed_ms`, + `connection_stats`, and `odbc_driver_version` do not exist for a live run at + any point. The Results page was built around the final JSON and currently + fills the gaps from the terminal progress event plus, when Runtime messages + is selected, the querystats snapshot. That leaves a live run without server + statistics showing fewer panels than a final-results run of the same + workload. Options worth weighing: have the engine emit a terminal summary + event on the stream, allow a results file alongside `-stream-json`, or give + the Results view an explicit live-run layout instead of hiding panels. +- **Revisit a derived average duration for runs without server statistics.** + The live monitor shows measured duration only when Runtime messages is + selected, because that is the only mode where the engine writes per-execution + timings. A derived figure (concurrency divided by completion rate) was built + and then removed: it matched the measured value to 1.3% while every connection + stayed busy, but overstated by 346% once threads began finishing at staggered + times, since it keeps dividing by connections that are no longer working. It + is also wrong whenever workload think time is set. Worth revisiting only with + a reliable in-flight count to divide by. + +### Microsoft Entra authentication coverage + +- ~~**Fix sqlpysim silently falling back to interactive sign-in.**~~ Implemented. + sqlpysim now accepts the same four case-insensitive `-A` values as sqlsim: + `ActiveDirectoryInteractive`, `ActiveDirectoryIntegrated`, + `ActiveDirectoryMsi`, and `ActiveDirectoryServicePrincipal`. Unknown values + fail instead of becoming interactive, and MSI and service-principal + credential rules match sqlsim. +- **Investigate matching go-sqlcmd's Entra method coverage.** go-sqlcmd v1.10 + accepts fifteen `--authentication-method` values; sqlsim accepts four. The gap + exists because go-sqlcmd uses the Go driver plus `azidentity`, while sqlsim + goes through ODBC Driver 18, so parity may not be achievable. Confirm which + are reachable through the driver before promising any of them. + + | Method | go-sqlcmd | sqlsim | + | --- | --- | --- | + | `ActiveDirectoryInteractive` | Yes | Yes | + | `ActiveDirectoryIntegrated` | Yes | Yes | + | `ActiveDirectoryServicePrincipal` | Yes | Yes | + | Managed identity | `ActiveDirectoryManagedIdentity` | `ActiveDirectoryMsi` | + | `ActiveDirectoryDefault` | Yes | No | + | `ActiveDirectoryAzCli` | Yes | No | + | `ActiveDirectoryDeviceCode` | Yes | No | + | `ActiveDirectoryPassword` | Yes | No | + | `ActiveDirectoryWorkloadIdentity` | Yes | No | + | `ActiveDirectoryClientAssertion` | Yes | No | + | `ActiveDirectoryAzurePipelines` | Yes | No | + | `ActiveDirectoryEnvironment` | Yes | No | + | `ActiveDirectoryAzureDeveloperCli` | Yes | No | + | `ActiveDirectoryServicePrincipalAccessToken` | Yes | Partly, via `-T` | + + Highest value first if the driver allows it: + - `ActiveDirectoryAzCli` reuses an existing `az login`, removing the + acquire-and-paste token step the documentation currently recommends. + - `ActiveDirectoryDefault` tries the whole credential chain, so one mode works + on a workstation, in CI, and on an Azure host. + - `ActiveDirectoryDeviceCode` gives headless Linux and macOS an interactive + path, which `ActiveDirectoryInteractive` cannot provide off Windows. +- **Consider accepting go-sqlcmd's method spellings as aliases.** Translating a + working `sqlcmd` command to sqlsim fails on managed identity because the + spelling differs. Accepting `ActiveDirectoryManagedIdentity` as an alias for + `ActiveDirectoryMsi` would remove a predictable papercut. +- **Persist run history across sessions.** History is in-memory and bounded, so + Compare lists only the current session's runs. Exporting each run's JSON and + using Compare's **Import JSON** or `comparison-report.ps1` is the current + workaround. +- **Run the live Studio browser tests in CI.** `sqlsim Studio CI` runs on pull + requests and pushes to `main` and covers the offline checks, including the + interface, configuration, and responsive Playwright suites. The live suites + (`studio.spec.cjs`, `packaged-replay.spec.cjs`, and `full-test-suite.ps1` + without `-OfflineOnly`) need a SQL Server and still run only on demand. +- **Cover Studio's error interface in the browser tests.** `full-test-suite.ps1` + covers the API rejection paths, but no test yet asserts that an error toast + appears and persists, that a failed run turns the result banner red, or that + the failure reason is shown without opening the log drawer. + +### Performance follow-ups + +Found in the pre-launch performance review. User-visible effects are documented +in [RELEASE-NOTES.md](RELEASE-NOTES.md); the rest are internal improvements. + +- **Keep latency as running statistics.** Fixes "Very long, high-rate runs + keep growing in memory" in [RELEASE-NOTES.md](RELEASE-NOTES.md). Replace the + per-execution samples in both engines with running totals or a fixed-size + histogram, which would also allow publishing p50/p95/p99. +- **Start sqlpysim workers together.** Fixes "sqlpysim threads start as they + connect" in [RELEASE-NOTES.md](RELEASE-NOTES.md). Add a start barrier like + sqlsim's. +- **Send Studio poll deltas.** Each 350 ms poll returns and re-renders up to 500 + log rows and the full live query table, and the server re-reads the query + statistics snapshot for every stream event. Send only new entries and skip + unchanged snapshots. +- **Cap remaining unbounded lists.** sqlsim keeps every failure message for the + end-of-run console summary outside JSON mode; Studio's connection test reads + engine output whole; and the Query Store snapshot query has no row limit. +- **Linear report generation.** `execution-report.ps1` and + `querystats-chart.ps1` build HTML and arrays with `+=` in loops, which is + quadratic on large result files. Use `StringBuilder` and lists, and cap the + chart to the top queries. + +## Under consideration + +- **Validate server certificates by default.** sqlsim, sqlpysim, and Studio + currently skip certificate validation unless the user opts in; see + "Certificate validation is off unless you ask for it" in + [RELEASE-NOTES.md](RELEASE-NOTES.md). Changing the default would protect + credentials and tokens from interception but breaks connections to servers + with self-signed certificates, so it needs a major-version decision, a + migration note, and a Studio warning when trust is enabled for a remote + server. +- **Reassess release signing and provenance if distribution expands.** The + current sample/Public Preview tools can remain unsigned while their limited + distribution does not justify certificate, identity-validation, and signing + infrastructure. Revisit this if SmartScreen warnings become a support + burden, enterprise customers require a verified publisher or application + allow-listing, or the tools move beyond sample/preview use. Windows would use + Authenticode through Azure Artifact Signing for executables produced by this + repository. Linux would use authenticated checksums and build provenance for + release archives rather than per-ELF signing. Public macOS distribution + remains separately gated on Developer ID signing and notarization. +- **Additional workload simulators.** TPC-inspired transactional and analytical + workloads, and a vector search simulator. See the Futures section of + [PROJECT-GUIDE.md](PROJECT-GUIDE.md) for what each would measure. Any + benchmark-inspired workload would use original schemas and scenarios and + report only its own measured results. +- **Optional color themes for sqlsim Studio.** The default theme would remain. + Any additional theme must meet WCAG AA contrast, preserve semantic success, + warning, and error colors, and render consistently across current browsers. + +## Release-note issues under investigation + +Issues affecting released versions are documented in +[RELEASE-NOTES.md](RELEASE-NOTES.md), including issues under investigation for +possible future releases.

It is untested and unsupported; use `-U/-P` or `-T` on Linux. + +### sqlsim Studio + +- Studio runs workloads through the `sqlsim` and `sqlpysim` engines above, so their driver policy applies to workload execution. +- Studio uses `Microsoft.Data.SqlClient` 7.1.0 only to collect Query Store statistics. It is compiled into the self-contained Studio executable; users do not install it. +- The Windows x64 Studio full GUI suite passed 91/91 on 2026-10-12 against SQL Server 17.0.4085.5. +- `Microsoft.Data.SqlClient` updates are taken by rebuilding Studio and rerunning its full suite; they ship only in a new Studio release. + +## Newer Driver Versions + +sqlsimtools targets driver families, not specific builds. `sqlsim` requests +`ODBC Driver 18 for SQL Server` by name and supports any 18.x release at or +above the 18.0 floor. `sqlpysim` supports `mssql-python` 1.x. + +Newer releases within those families are expected to work and are generally safe +to use, but only the versions listed under Current Baseline have been validated +by this project. Until a newer version appears in that list, treat it as +supported on a best-effort basis: it is not blocked, and it has not been tested +here. Report a regression as a GitHub issue and include the exact driver version. + +A new major driver version, such as a future ODBC Driver 19 or `mssql-python` +2.x, is unsupported until it is validated and recorded here. + +Because these tools measure performance, the client driver is part of the +measurement environment. `sqlsim` records `odbc_driver_version` in its JSON +output and `sqlpysim` reports the `mssql-python` version it loaded. Pin your +driver version for any comparison you intend to keep. sqlsim Studio Compare and +`comparison-report.ps1` show a driver difference as an informational +difference: they still compare the runs, but a driver change can explain part +of any performance change and should be held constant when it is not what you +are testing. + +## Validation Matrix for Releases + +Before tagging a release: + +1.

Only drivers with changed versions run their platform-specific offline smoke job. +3. The workflow opens or updates one issue with detected versions and smoke results, assigned to a maintainer for notification. +4.

The destination is always the database selected in +Configure. If the trace contains one captured `database_name`, Studio redirects +that context to the selected destination when it stages the private Replay XML. +The converted file does not need a hand-authored target attribute. + +Studio rejects captures containing multiple distinct databases during file +preflight. Source-to-target mapping for multi-database Replay is tracked in +[BACKLOG.md](BACKLOG.md) for a future release. + +Studio validates target connectivity, not schema or data equivalence. Users are +responsible for synchronizing target schema and data before interpreting +performance comparisons. Server configuration, indexes, statistics, cache +state, concurrency, and Query Store activity can also affect results. + +### sqlpysim does not yet have full sqlsim CLI or output compatibility + +`sqlpysim` is in **Public Preview**. These compatibility gaps remain and are +tracked for future releases. + +`sqlpysim` supports the shared core workflow: connection tests, `-Q` and `-i` +query execution, `-workload` mixed workload groups with per-group threads, +iterations, think time, duration mode and ramp-up, concurrent threads and +iterations, reconnect mode, text, JSON and `-stream-json` live event output, +and `-querystats` aggregates with optional `-querystats-interval` snapshots. +It does not yet implement the entire `sqlsim` command surface or every +low-level client measurement. + +The following `sqlsim` options are unavailable in `sqlpysim`: + +- `-replay` and `-replayfile` for fast or stress replay of converted XEvent + traces. Replay is deliberately deferred from the sqlpysim v1.0 Public + Preview because matching sqlsim requires a substantial session-aware + scheduling, RPC fidelity, metrics, and testing subsystem. Future support may + be considered; use `sqlsim` for replay. +- `-F` for overriding the hostname used during certificate validation + +Some accepted options also differ in effect: + +- `-p` prints a warning and runs unprepared. `mssql-python` prepares only + executions with bound parameters, while sqlpysim workloads contain complete + SQL text and expose no parameter-binding source. This cannot reproduce + sqlsim's prepare/execute mode for raw SQL. +- `-app` is rejected. The driver reserves the application name and always + reports `MSSQL-Python` to the server, so a requested name can never take + effect. This is documented driver behavior rather than a `sqlpysim` + limitation: see + [Connection strings for mssql-python](https://learn.microsoft.com/sql/connect/python/mssql-python/connection-strings), + which lists `APP` as reserved and `Application Name` as unrecognized. + `sqlpysim` refuses the option and reports `MSSQL-Python` as the application + name, which is what `APP_NAME()` returns, so a session can be found by the + name shown. Earlier versions accepted `-app` and echoed the requested name + back in text and JSON while the server saw something else. Use `sqlsim` when + the application name matters. `sqlsim Studio` disables its Application name + field for the Python engine for the same reason. +JSON output remains suitable for tool-specific automation but is not an +identical metrics contract. The document uses the same driver, configuration, +warning, and verbose-operation field names as `sqlsim`, while retaining +engine-specific values such as `odbc_driver: "mssql-python"`. Both tools report +query execution time through result consumption and report zero fetch +operations in JSON mode. `sqlpysim` now derives `-querystats` aggregates from +the same `SET STATISTICS TIME/IO` diagnostic path as `sqlsim`. + +Use `sqlsim` when any unavailable option, exact validation behavior, prepared +execution, or an identical metrics contract is required. Compatibility work is +tracked in [BACKLOG.md](BACKLOG.md). + +`sqlpysim` also spends more client CPU per query than `sqlsim`. In pre-release +measurements against a local server, a trivial `SELECT 1` used about 15 times +the client CPU per execution, and at 50 threads `sqlpysim` reached roughly a +tenth of `sqlsim`'s throughput because Python threads share one interpreter +lock. For light queries the client, not SQL Server, becomes the limit. Use +`sqlpysim` to measure `mssql-python` driver behavior, and `sqlsim` when you +need maximum load or are comparing server-side performance. + +### sqlsim Studio ships only controls that work + +sqlsim Studio v1.0 omits unimplemented features from the interface rather than +showing them greyed out. A visible button always does something. + +All six authentication modes are wired: Windows integrated, Microsoft Entra +token, Microsoft Entra interactive, managed identity, service principal, and SQL +authentication. Studio shows only the credential fields a mode uses and enforces +the same rules the engines do, so an unusable combination is refused before a +process starts. + +One option disables itself where the capability genuinely does not exist: + +| Option | Unavailable when | Reason | +| --- | --- | --- | +| Microsoft Entra interactive | Studio runs on Linux or macOS | ODBC Driver 18 implements interactive sign-in on Windows only | + +For repeated runs against Azure SQL, prefer **Microsoft Entra token**. Each +connection under interactive sign-in can prompt, which does not suit a +high-connection workload: + +```powershell +az account get-access-token --resource https://database.windows.net --query accessToken -o tsv +``` + +Planned for a future preview revision, currently absent from the interface: +copying the Monitor event stream, Run again, opening a completed run's +configuration, and copying, exporting, or clearing the execution log display. +The log itself works; only those actions are missing. + +Some controls start disabled and enable themselves when they become meaningful — +Stress connections in stress replay, Connection pooling once Reconnect each +iteration is on, Suppress result rows in console telemetry, Stop run during a +run, and the comparison selectors once a final result exists. Those are +working as intended, not gaps. + +**HTML reporting is a two-step flow, not a Studio button.** Studio exports the +canonical results JSON with the verbose fields included, and +`sqlsim/examples/reports/execution-report.ps1` turns that file into an HTML +report. The Compare view likewise exports a comparison bundle that +`sqlsim/examples/reports/comparison-report.ps1` renders as an A/B report. A +single generator serves both the command line and Studio rather than two +implementations that drift apart. + +**Studio run history is session-scoped.** It is held in memory and discarded +when Studio exits. To compare across sessions, export each run's JSON and use +**Import JSON** in the Compare view, or pass the two files to +`comparison-report.ps1 -BaselineFile -CandidateFile ` for an HTML report. + +The three authentication modes are the most consequential. `sqlsim` and +`sqlpysim` support all of them through `-A`; only the Studio wiring is +outstanding. **Use Microsoft Entra token instead**, which is fully implemented +and is the recommended path for Azure SQL Database, Azure SQL Managed Instance, +and SQL database in Microsoft Fabric: + +```powershell +az account get-access-token --resource https://database.windows.net --query accessToken -o tsv +``` + +Some controls start disabled and enable themselves when they become meaningful — +Stress connections in stress replay, Connection pooling once Reconnect each +iteration is on, Suppress result rows in console telemetry, Stop run during a +run, and the comparison selectors once a final result exists. Those are +working as intended, not gaps. + +Studio run history is held in memory for the current session only. It is +discarded when Studio exits; use **Export JSON** and **Import JSON** to compare +results across sessions. + +### Microsoft Entra interactive authentication is Windows-only + +`-A` (and `-A ActiveDirectoryInteractive`) works on Windows only. Both `sqlsim` +and `sqlpysim` reject it on Linux and macOS during argument validation: + +```text +ActiveDirectoryInteractive is not supported by ODBC Driver 18 on Linux. +``` + +The cause is Microsoft ODBC Driver 18, which implements interactive Entra sign-in +only on Windows. Rejecting early is deliberate and avoids a hang on headless +hosts. + +**Use instead on Linux and macOS:** + +- `-T ` — an access token, for example from + `az account get-access-token --resource https://database.windows.net --query accessToken -o tsv` +- `-A ActiveDirectoryMsi` — a managed identity + +### Certificate validation is off unless you ask for it + +`sqlsim` follows the same negotiation rule as `sqlcmd` (Go): with neither `-N` +nor `-C` the server certificate is **not validated**, `-N` without `-C` +requires validation, and `-C` bypasses it. A bare +`sqlsim -S localhost -E` therefore connects to a server with a self-signed +certificate, where `sqlcmd` (ODBC) 18 and later would refuse. + +This is deliberate, matching the documented `sqlcmd` (Go) behavior, but it is +easy to carry into production unnoticed. **For Azure SQL and any connection +that leaves the host, pass `-N m` or `-N s`.** Azure presents a certificate +from a trusted authority, so validation costs nothing and the connection +crosses the internet. + +The rule applies to every authentication mode, including access token +authentication (`-T`). `-T` on its own connects without validating; add `-N m` +to opt in. + +`sqlpysim` follows the same default. sqlsim Studio starts with **Trust server +certificate** checked, matching SQL Server Management Studio, and uses the same +setting for Query Store collection. Clear it for Azure SQL or any server with a +certificate from a trusted authority. + +`-F ` sets the name the certificate is checked against, for a server +reached by an IP address, a DNS alias, or an availability-group listener. It +cannot be combined with `-C`. sqlsim supports `-F`; sqlpysim does not expose +the option in v1.0. Support will be investigated for a future release. + +### `-p` (prepared statements) is ignored by sqlpysim + +`sqlsim` executes complete SQL text through `SQLPrepare` / `SQLExecute` without +requiring bound parameters. `mssql-python` takes its prepare path only for +executions with bound parameters, while sqlpysim workloads expose no +parameter-binding source. `sqlpysim` therefore prints a warning and runs the +workload unprepared: + +```text +Warning: Prepared statements (-p) are not supported for raw SQL workloads by mssql-python; flag ignored +``` + +Timings taken with `-p` are therefore comparable between `sqlpysim` runs, but not +between `sqlpysim` and `sqlsim`. + +Parameterized sqlpysim workloads, including a format for supplying bound values, +may be considered for a future release. They are not part of the v1.0 Public +Preview contract. + +### sqlpysim's ODBC driver version is pinned by its wheel, not the operating system + +Both tools connect through Microsoft ODBC Driver 18, but they get it from +different places. `sqlsim` loads the driver installed on the host. `sqlpysim` +loads the copy vendored inside `mssql-python`, which hard-pins +`mssql-python-odbc`. + +The two can differ — a host with `msodbcsql18` 18.7.1.1 installed still runs +`sqlpysim` on the bundled 18.6.2.1. Updating the system package does not move +`sqlpysim`; that requires a newer `mssql-python` release. + +### Very long, high-rate runs keep growing in memory + +`sqlsim` and `sqlpysim` keep one latency sample per query execution until the +run ends. `sqlsim` stores 8 bytes per execution, so a run executing about 70,000 +queries per second grows by roughly 2 GB per hour; at a few thousand executions +per second the growth is about 100 MB per hour. `sqlpysim` grows about +0.3 MB per second at its typical rates. Memory is released when the run ends. + +For multi-hour runs of very fast queries, watch client memory, or split the +test into shorter runs. Query statistics (`-querystats`) no longer add +per-execution memory. Replacing the samples with running statistics is tracked +for a future release. + +### sqlpysim threads start as they connect + +`sqlsim` opens every connection first and then releases all threads together, +so its measurement window starts with full concurrency. `sqlpysim` starts each +thread as soon as its own connection opens, so the first moments of a run have +fewer active threads. On long runs the difference is negligible; on runs of a +few seconds it can lower `sqlpysim` throughput compared with `sqlsim`. Run +cross-tool comparisons long enough that connection time is a small fraction of +the run. A start barrier is tracked for a future release. diff --git a/SECURITY.md b/SECURITY.md new file mode 100644 index 0000000..656f791 --- /dev/null +++ b/SECURITY.md @@ -0,0 +1,14 @@ + + +## Security + +Microsoft takes the security of our software products and services seriously, which +includes all source code repositories in our GitHub organizations. + +**Please do not report security vulnerabilities through public GitHub issues.** + +For security reporting information, locations, contact information, and policies, +please review the latest guidance for Microsoft repositories at +[https://aka.ms/SECURITY.md](https://aka.ms/SECURITY.md). + + diff --git a/SUPPORT.md b/SUPPORT.md new file mode 100644 index 0000000..d2d5c07 --- /dev/null +++ b/SUPPORT.md @@ -0,0 +1,20 @@ +# Support + +## How to file issues and get help + +This project uses [GitHub Issues](https://github.com/microsoft/sqlsimtools/issues) to track reproducible bugs and scoped feature requests.

Four ways to work

+

Start visually, automate from the command line, compare drivers, or describe the experiment in plain language.

+
+
+
+ 1 +

sqlsim Studio

+

Configure, monitor, replay, and compare workloads in a self-contained local browser app.

+ Explore Studio → +
+
+ 2 +

sqlsim

+

Native C++ and ODBC for low-overhead scripts, concurrent load tests, and replay.

+ Read the CLI guide → +
+
+ 3 +

sqlpysim

+

A Python workflow powered by Microsoft's mssql-python driver for automation and comparison.

+ See Python examples → +
+
+ 4 +

Workload Builder

+

Use GitHub Copilot and other agents to design and compare experiments from plain-language requests.

+ Use with agents → +
+
+
+ +
+
+
+

One toolkit, every SQL Server target

+

Use the same workload patterns across local development, Azure, and Microsoft Fabric.

+
+
+
✓SQL Server 2019, 2022, and 2025
+
✓Azure SQL Database and Managed Instance
+
✓SQL database in Microsoft Fabric
+
✓Windows and Ubuntu Public Preview paths
+
+
+
+ +
+
+

From download to first result

SQL batches are separated by `GO`. Use `-stoponerror` to halt all threads on the first failure (default: continue). + +## Rules +1. Resolve the executable using the discovery order above. Do not search source build directories. +2. Never append `2>&1`, `>`, or `| Select-String` to a sqlsim invocation. Capture into a variable instead. +3. Parse JSON results with `ConvertFrom-Json`. Compute deltas between phases — never compare cumulative values. +4. For Azure SQL prefer `-T ` over `-A` for repeated runs. +5. On Linux, do not use bare `-A` or `ActiveDirectoryInteractive`; use `-T`, Kerberos integrated authentication, managed identity, service principal, or SQL authentication. +6. `-querystats-interval ` snapshots query statistics to a file while the run is in progress, implying `-querystats` and defaulting to `querystats-live.json`. The file is replaced atomically, so it is safe to poll. A write failure never fails the run and is reported once on stderr, but that message is suppressed in `-json` and `-stream-json` modes; verify the file exists rather than relying on a message or the exit code. +7. Combine `-stream-json` with `-json -o ` to keep live NDJSON on stdout and write the canonical final JSON to the file. The combined mode requires `-o`. +8. Certificate validation follows `sqlcmd` (Go): neither `-N` nor `-C` means the certificate is not validated, `-N` without `-C` requires validation, and `-C` bypasses it. This applies to every authentication mode including `-T`. For Azure SQL prefer `-N m`; use `-C` only for a self-signed server, or `-F ` when the connected name differs from the certificate name. +9. Start load tests with a small `-n` value and scale gradually while monitoring client and server CPU, memory, network, and connection usage. High thread counts can exhaust client resources and invalidate results; use a dedicated client for significant load tests. diff --git a/release/OverlayInstall.psm1 b/release/OverlayInstall.psm1 new file mode 100644 index 0000000..42daf91 --- /dev/null +++ b/release/OverlayInstall.psm1 @@ -0,0 +1,210 @@ +# Shared by sqlsim/publish.ps1 and sqlpysim/publish.ps1 to install a release +# overlay into a project without silently overwriting or deleting its files. +# +# A plan lists every file the overlay installs.

Combine it with `-json -o ` to retain the +canonical final result while streaming. Counters are cumulative and +`throughput_per_second` is a running average, so a consumer wanting a current +rate computes deltas between events. +After the first successful connection, progress and completed events also +identify the driver version and SQL Server version and edition. + +`-querystats-interval ` writes a statistics snapshot to a file while +the run is in progress, implying `-querystats` and defaulting the path to +`querystats-live.json`.

The tools are not fully CLI- or +JSON-schema-compatible, so pin the tool used by the pipeline and validate +parsers against its output.

Keep it representative and deterministic, favour the statements whose performance you care about, and avoid output that depends on wall-clock time or identity values. + +```sql +-- workload.sql — a representative slice of your workload. +-- Replace these with the statements whose performance you care about. +SELECT TOP (100) * +FROM dbo.Orders +WHERE OrderDate >= DATEADD(DAY, -30, SYSUTCDATETIME()) +ORDER BY OrderDate DESC; +GO + +SELECT CustomerId, COUNT(*) AS Orders +FROM dbo.Orders +GROUP BY CustomerId; +GO +``` + +## Step 2 — Invoke `sqlpysim` + +Point `sqlpysim` at the target database, set the concurrency, and capture the `-json` document. Run it a few times and take the **median** to damp run-to-run noise on a shared runner. + +```bash +python sqlpysim.py \ + -c "$SQL_CONNECTION_STRING" \ + -i workload.sql \ + -n 8 \ + -r 100 \ + -json \ + -q > result.json +``` + +| Flag | Meaning | +|---|---| +| `-c` | Full connection string to the target database (a single value, ideal for a CI secret). | +| `-i` | Workload `.sql` replayed under load. | +| `-n` | Concurrent threads. | +| `-r` | Iterations per thread. | +| `-json` | Emit the aggregate metrics document to stdout. | +| `-q` | Quiet, so stdout contains only the JSON. | +| `-o ` | Optional: write the JSON to a file instead of stdout. | + +> **Auth alternatives.** Instead of a connection string you can use discrete flags, shared with `sqlsim`: `-S -d ` plus one of `-E` (Windows), `-A` (Entra interactive), `-T ` (access token), or `-U -P ` (SQL auth), and `-C` to trust the server certificate for a container. Prefer `-c` with a single secret in CI. + +## Step 3 — Wire it into GitHub Actions + +A complete, opt-in job.

The fields a workload gate cares about: + +```jsonc +{ + "success": true, + "configuration": { "total_batches": 800 }, + "metrics": { + "total_runtime_seconds": 12.42, + "total_query_execution_time_seconds": 95.1, + "errors": { "total": 0, "list": [] } + } +} +``` + +Derive the two headline numbers with `jq`, and fail fast if the workload itself errored: + +```bash +throughput=$(jq '.configuration.total_batches / .metrics.total_runtime_seconds' result.json) +avg_latency_ms=$(jq '(.metrics.total_query_execution_time_seconds / .configuration.total_batches) * 1000' result.json) +errors=$(jq '.metrics.errors.total' result.json) + +echo "throughput=${throughput} batches/s avg_latency=${avg_latency_ms} ms errors=${errors}" +[ "$errors" -eq 0 ] || { echo "workload reported errors"; exit 1; } +``` + +## Step 5 — Compare against a baseline + +A single number means little; a **delta** is the signal. Establish a baseline (the target branch) and compare the candidate against it: + +1. Run the workload on the **base branch**, or download a stored baseline artifact, into `baseline.json`. +2. Run it on the **candidate** into `result.json`. +3. Compute the percentage change and compare to a threshold. + +```bash +base=$(jq '.configuration.total_batches / .metrics.total_runtime_seconds' baseline.json) +cand=$(jq '.configuration.total_batches / .metrics.total_runtime_seconds' result.json) +delta=$(python -c "print(( $cand - $base ) / $base * 100)") + +echo "throughput delta: ${delta}%" +python -c "import sys; sys.exit(1 if $delta < -25 else 0)" \ + || echo "::warning::workload throughput regressed by more than 25%" +``` + +Using `::warning::` keeps the gate **advisory** (see the next section). Swap it for a non-zero `exit` to make it blocking once you trust the signal. + +## Signal fidelity: advisory vs. deterministic gating + +`sqlpysim` reports **aggregate throughput and latency**, a timing-tier signal that is inherently noisy from run to run on a shared runner (noisy neighbours, cold caches, virtualization). Treat a regression here as **advisory**: warn on the PR, do not fail the build on wall-clock alone. Taking the median of several passes and comparing relative deltas, not absolute milliseconds, makes it far more stable. + +For a more stable pass/fail signal, use per-query **logical reads** from +`-querystats`. Both sqlpysim and sqlsim emit the same query-statistics fields, +so a pipeline can compare read counts without relying only on shared-runner wall +clock time. Neither tool currently emits a query or plan hash. + +| Signal | Source | Reproducible? | Use as | +|---|---|---|---| +| Throughput (batches/s) | `sqlpysim` / `sqlsim` | No (timing) | Advisory | +| Average latency (ms) | `sqlpysim` / `sqlsim` | No (timing) | Advisory | +| Logical reads | `sqlpysim -querystats` / `sqlsim -querystats` | Usually | Gate with tolerance | + +## Tuning and best practices + +- **Isolate the target.** Always run against a throwaway or purpose-provisioned database, never a shared or production instance. The workload is destructive to caches and plan state. +- **Median of N.** Run the workload three to five times and take the median; a single pass is easily skewed. +- **Right-size concurrency.** Set `-n` to a concurrency that resembles production and `-r` high enough that the run lasts several seconds; too-short runs are dominated by startup noise. +- **Warm up.** The first execution pays plan-compilation and cache-fill costs. A short discarded warm-up pass before the measured passes yields steadier numbers. +- **Compare relatively.** Gate on percentage delta versus a baseline, not absolute timings, so results survive moving to a different runner size. +- **Pin everything.** Pin the `sqlpysim` release, the Python version, and the SQL Server image tag, so a CI regression reflects your change and not a moving dependency. + +## Troubleshooting + +| Symptom | Likely cause / fix | +|---|---| +| `result.json` is empty or not valid JSON | Ensure `-q` is set and stdout is captured; without `-q`, progress lines interleave with the JSON. | +| `ModuleNotFoundError: mssql_python` | `pip install mssql-python` in the same job; Python 3.10+. | +| Connection or TLS failure against a container | Trust the server cert: `-C`, or `TrustServerCertificate=Yes` / `Encrypt=Optional` in the connection string. | +| Wildly varying throughput | Expected on shared runners; rely on median plus relative delta and keep the gate advisory. | +| `errors.total > 0` | Inspect `metrics.errors.list`; usually a workload query referencing objects the seed did not create. | + +## Moving to native `sqlsim` + +When a native `sqlsim` build exists for your runner OS, the switch is minimal: +sqlsim accepts the same core flags (`-i`, `-n`, `-r`, `-json`, and +`-querystats`) and emits the same query-statistics JSON fields. Point the +pipeline at the sqlsim binary instead of `python sqlpysim.py`; the parsing and +logical-read gate can stay the same. + +## References + +- [`sqlpysim` README](https://github.com/microsoft/sqlsimtools/blob/main/sqlpysim/README.md) and [user manual](../../sqlpysim.md) +- [`sqlsim` user manual](https://github.com/microsoft/sqlsimtools/blob/main/sqlsim/sqlsim.md) — for `-querystats` and deterministic signals +- [`mssql-python` driver](https://github.com/microsoft/mssql-python) +- [GitHub Actions: about service containers](https://docs.github.com/actions/using-containerized-services/about-service-containers) diff --git a/sqlpysim/examples/powershell/README.md b/sqlpysim/examples/powershell/README.md new file mode 100644 index 0000000..d084690 --- /dev/null +++ b/sqlpysim/examples/powershell/README.md @@ -0,0 +1,52 @@ +# PowerShell Example Scripts + +Scripts that run the [SQL examples](../sql/README.md) with common +authentication and load patterns.

It shares sqlsim's core query, concurrency, authentication, and reporting workflow while leveraging Microsoft's native mssql-python driver. Advanced CLI modes and some output fields differ; see [sqlpysim vs sqlsim - What's Different?](#sqlpysim-vs-sqlsim---whats-different) and the repository [release limitations](https://github.com/microsoft/sqlsimtools/blob/main/RELEASE-NOTES.md#sqlpysim-does-not-yet-have-full-sqlsim-cli-or-output-compatibility). + +**⚠️ Important:** sqlpysim is a **testing and workload simulation tool** designed for development, testing, and performance evaluation environments. It is **NOT intended for use against production systems**. Running sqlpysim with high thread counts (`-n`) can consume substantial CPU, memory, network bandwidth, and database connections on the client and server. Excessive concurrency can make the client unresponsive, exhaust resources, and distort benchmark results before the database reaches its limit. Start with a small thread count, increase it gradually, and monitor both client and server resources. Use dedicated test environments and, for significant load tests, a dedicated client machine. + +**How This Tool Was Built:** +100% of the code, scripts, and documentation for sqlpysim was developed with GitHub Copilot in Visual Studio Code using various AI models, orchestrated by Bob Ward. + +**Key Capabilities:** +- Cross-platform: Windows and Ubuntu Linux in Public Preview, with macOS ARM64 in Private Preview +- Single Python file (no installation required beyond Python and driver) +- Native builds leverage Microsoft's official mssql-python driver +- Familiar sqlsim-style CLI and output conventions for shared core workflows +- Execute single queries or SQL script files +- Multi-threaded workload simulation +- Multiple authentication methods (Windows, Entra, SQL Auth, Access Token, Managed Identity) +- Detailed performance metrics (connection time, query execution, percentiles) +- Per-query server statistics compatible with sqlsim (`-querystats`) +- Timeout controls for connections and queries +- TDS 8.0 encryption support +- Connection behavior controls (reconnect mode) +- Support for read replicas and Always On Availability Groups +- Full Unicode support (UTF-8 input and output) +- Support for local SQL Server, Azure SQL Database, Azure SQL Managed Instance, and SQL database in Fabric + +**Top 10 Cool Things You Can Do with sqlpysim:** + +| # | Cool Thing | Why It's Unique | +|---|------------|-----------------| +| **1** | **Cross-platform stress testing** | Run the same workload tests on Windows and Ubuntu Linux, or help validate macOS ARM64 through the Private Preview | +| **2** | **Zero compilation - just Python** | Single .py file, runs anywhere Python 3.10+ is installed | +| **3** | **Full Entra authentication support** | Interactive, Managed Identity, Service Principal, and more | +| **4** | **Familiar sqlsim-style output** | Use common metrics concepts across the C++ and Python tools while accounting for documented schema differences | +| **5** | **Test Azure SQL with modern auth** | Full Managed Identity support (ActiveDirectoryMsi) | +| **6** | **Separate connection time from query time** | Understand *where* time is spent - network, auth, or query | +| **7** | **Export results as JSON** | Machine-readable output for CI/CD pipelines | +| **8** | **Get detailed percentiles (P50, P95, P99)** | Know your real latency distribution, not just averages | +| **9** | **Native driver performance** | mssql-python is Microsoft's official native driver | +| **10** | **Per-query server statistics** | Compare server CPU, elapsed time, and reads per query using the same fields as sqlsim (`-querystats`) | + +[↑ Back to Table of Contents](#table-of-contents) + +## Installation + +### Prerequisites + +sqlpysim requires Python 3.10 or higher and the Microsoft mssql-python driver. + +**Supported Platforms:** + +sqlpysim targets the same platforms as sqlsim. + +| Platform | Architectures | Requirements | +|----------|---------------|--------------| +| Windows | x64, ARM64 | ARM64 requires Python 3.11 or later | +| Ubuntu 24.04 / 26.04 LTS | x64 | Python 3.10 or later | + +macOS ARM64 is available through the Private Preview; see `MACOS-PRIVATE-PREVIEW.md` +in the package. `mssql-python` also publishes wheels for Linux ARM64 and +musl-based distributions.

Connection:** + - `-S <server>` (optional, defaults to localhost) + - Authentication method: `-E`, `-A`, `-T`, or `-U/-P` (one required) + +**2. Query Source (optional):** + - `-Q <query>` for a single query, OR + - `-i <file>` for a SQL script file + - If omitted, performs connection test only + +**3. Database (optional):** + - `-d <database>` (optional for SQL Server, required for Azure SQL Database) + +**4.

The plan result is consumed internally and is never included +in query rows or JSON. This mode does not query DMVs, require server-state +permissions, or emit query/plan hashes. + +`-stream-json` replaces the single JSON document with a stream of events, one +compact JSON object per line on stdout, matching sqlsim's shape and cadence. +It turns on JSON mode. Events go to stdout even when `-o` is supplied, because +the stream is a channel for a supervising process rather than part of the run's +recorded output. + +Combine `-stream-json` with `-json -o <file>` to retain the complete canonical +result while streaming. NDJSON remains on stdout and the final JSON document is +written to the file after completion. The combined mode requires `-o` so the +two JSON formats never share one channel. + +| Event | When | Fields | +|-------|------|--------| +| `started` | Once, before the first connection | `type`, `timestamp`, `version`, `threads` | +| `progress` | Every second while running | `type`, `timestamp`, `elapsed_seconds`, connection and execution counters, `errors`, `throughput_per_second`, and, after the first successful connection, `odbc_driver_version`, `server_version`, and `server_edition` | +| `completed` | Once, after the last thread finishes | The `progress` fields plus `status`, either `success` or `error` | + +Counters are cumulative, and `throughput_per_second` is the running average +since the run began rather than an instantaneous rate; a consumer wanting a +current rate computes the delta between two events.

It implies `-querystats`. +`-querystats-file` sets the path, defaulting to `querystats-live.json` in the +working directory. + +A first snapshot is written immediately, then one per interval, then a final +one after the last thread finishes. The file is written to a temporary name in +the same directory and renamed over the target, so a reader never sees a +partially written file. + +A write failure never interrupts the workload: the run continues and the exit +code is unaffected. It is reported once on the normal error channel, so a +mistyped path does not look like a healthy run, and later failures stay quiet +so a per-interval timer cannot flood the output. That channel is silent in +`-json` and `-stream-json` modes, so machine-readable output is never +disturbed; in those modes check that the file exists rather than relying on a +message. `sqlsim` behaves the same way. + +Each snapshot carries `timestamp`, `elapsed_seconds`, +`execution_elapsed_seconds`, `throughput`, `peak_throughput`, and `status` +(`running` until the final snapshot, then `complete`), followed by `config`, +`connection_stats`, `query_stats` with the same per-query aggregates and +totals `-querystats` prints, `total_errors`, `total_warnings`, +`recent_errors`, and `recent_warnings`. + +`throughput` is measured over the execution window rather than the whole run, +so the connection phase does not depress it, and `peak_throughput` retains the +highest value seen across the run. + +```bash +python sqlpysim.py -S localhost -d AdventureWorksLT -E -C \ + -Q "SELECT TOP 100 * FROM SalesLT.Product" -n 4 -r 500 \ + -querystats-interval 5 -querystats-file live.json -q +``` + +`recent_warnings` retains the ten most recent structured ODBC warning entries, +matching the final JSON `metrics.warnings.list` contract. + +### Connection Options + +| Parameter | Description | Default | +|-----------|-------------|---------| +| `-C` | Trust server certificate explicitly | Without `-N`, certificates are trusted; with `-N`, certificates are validated | +| `-N [level]` | Encryption level (o=optional, m=mandatory, s=strict) | mandatory when `-N` is specified without a level | +| `-R <intent>` | Application intent (readonly/readwrite) | readwrite | +| `-M` | Enable MultiSubnetFailover | Off | +| `-l <seconds>` | Login timeout (0–86400) | 30 | +| `-t <seconds>` | Query timeout (0–86400) | 0 (no timeout) | +| `-app <name>` | Not supported: the driver reserves the application name | n/a | + +### Control Parameters + +| Parameter | Description | Default | +|-----------|-------------|---------| +| `-p` | Prepared statements (accepted with warning, not functional) | Off | +| `-stoponerror` | Stop on first error | Off | +| `-reconnect` | Reconnect for each iteration | Off | +| `-usepool` | Enable connection pooling (requires `-reconnect`) | Off | +| `-retry <count>` | Connection retry attempts (0–255) | 0 | +| `-retrydelay <seconds>` | Seconds between retries (1–60) | 10 | +| `-h`, `-?`, `--help` | Show help message | | +| `--version` | Show version information | | + +[↑ Back to Table of Contents](#table-of-contents) + +## Limits and Resource Considerations + +sqlpysim does not impose fixed size caps on SQL text, SQL script files, or +workload JSON files. Those inputs are memory-bound and remain subject to +operating-system, `mssql-python`, ODBC driver, and SQL Server limits. A missing +application cap does not mean an input or concurrency level is safe. + +### Input and Output Limits + +| Item | sqlpysim limit | Resource consideration | +|------|----------------|------------------------| +| Command-line query (`-Q`) | No explicit sqlpysim cap | The operating system's command-line length, available memory, driver behavior, and SQL Server batch limit still apply. Use `-i` for large scripts. | +| SQL script (`-i`) | No explicit file-size cap | The complete file is loaded into memory and split into batches before execution. | +| Workload JSON (`-workload`) | No explicit file-size cap | The complete JSON document is loaded into memory before parsing. | +| Script referenced by workload JSON | No explicit file-size cap | Each script is loaded into memory; workload expansion and high thread counts increase client memory use. | +| Inline query in workload JSON | No explicit per-query cap | Query text is held in memory and remains subject to SQL Server's batch limit. | +| Query result set when not using `-q` | No explicit row or byte cap | `mssql-python` fetches the result set into client memory before sqlpysim formats it. Use `-q` for load tests. | +| Text, JSON, and statistics output files | No explicit file-size cap | Available disk space is the effective limit. Verbose output and large error collections can grow quickly. | +| SQL batch sent to the server | SQL Server limit | SQL Server allows 65,536 times the negotiated network packet size per batch; the default 4 KB packet size is approximately 256 MiB. | +| Replay XML | Not supported | Use sqlsim for workload replay. | + +Use `GO` separators to split large scripts into smaller batches. Keep individual +batches well below the server maximum; very large batches increase client +memory, network traffic, compilation cost, and server memory use. + +### Numeric and Concurrency Limits + +| Item | Accepted range | Resource consideration | +|------|----------------|------------------------| +| Threads (`-n`) | 1 or greater; no explicit maximum | Each worker consumes Python and driver memory, scheduling capacity, network resources, and a database connection. | +| Iterations (`-r`) | 1 or greater; no explicit maximum | Total executions multiply by threads and batches. | +| Login and query timeouts (`-l`, `-t`) | 0 to 86,400 seconds | Zero uses the documented driver behavior for that option. | +| Retry count (`-retry`) | 0 to 255 | Retries can extend total runtime. | +| Retry delay (`-retrydelay`) | 1 to 60 seconds | Applied between connection attempts. | + +Workload-file groups add their thread counts together. Start with a small +thread count, scale gradually, and monitor CPU, memory, network, open +connections, and errors on both client and server. Stop scaling when the +client becomes saturated, because results beyond that point measure the load +generator rather than the database.

completed faster | +| **P99** | 99th percentile | Shows "long tail" latency | + +**Why percentiles matter more than averages:** + +- **Averages hide outliers**: A system with Avg=1ms but P99=100ms has serious tail latency +- **P95/P99 show real user experience**: If P99=500ms, 1 in 100 users experiences half-second delays +- **Identifies contention**: When P99 >> P50, it indicates resource contention under load + +**Example interpretation:** +``` +Execution Metrics: +Avg: 0.47 ms ← Average looks great +Min: 0.14 ms ← Best case +Max: 5.06 ms ← One outlier hit 5ms +P50: 0.32 ms ← Half completed in <0.32ms (better than avg!) +P95: 1.26 ms ← 95% completed in <1.26ms +P99: 3.50 ms ← 1% took >3.5ms (10x the median) +``` + +### JSON Output Mode (`-json`) + +Outputs results in structured

The login must be able to create + and drop `dbo.sqlsim_test_proc` in `tempdb` (SQL Server) or in the target + database (Azure SQL Database), and to read its own session from the DMVs. +- Azure SQL Database targets are detected by name.

The online checks replay `testing\replay-test-data.xml` against +the target with Windows authentication unless `-UseToken` or +`-Username`/`-Password` is supplied. + +### HTML Report Tests + +The report generators in `examples/reports/` render JSON results that may come +from another person. Run this offline test after changing a report generator: + +```powershell +.\test-reports.ps1 +``` + +It renders hostile result files with the comparison, execution, and query +statistics reports, and checks that text stays encoded and non-numeric metrics +cannot reach generated JavaScript. It also checks that `comparison-report.ps1` +uses the same metrics and configuration guardrails as sqlsim Studio Compare. +CI runs it in the PowerShell analysis job. + +### Full Test Suite Features + +- **130+ comprehensive tests** covering all functionality (varies based on options and environment) +- **Output format validation**: Comprehensive validation of non-verbose, verbose, and JSON output formats +- **Terminology verification**: Ensures consistent use of "batches" terminology (not "queries") +- **Automatic Azure detection**: Adjusts thread limits (500 for Azure, 1024 for on-prem) +- **TestReadReplica flag**: Enable tests for `-R` (read-only intent) and `-M` (multi-subnet failover) on servers with read replicas (adds 3 tests) +- **Warning category**: Read replica tests show warnings (not failures) if server doesn't have replicas configured +- **StopOnError flag**: Exit immediately on first failure for faster debugging +- **Output logging**: Write test results to file with start/end timestamps and duration +- **Separate output files**: Tests that use sqlsim's `-o` parameter create their own output files, not captured in the test transcript +- **Flexible authentication**: Windows, Entra ID (interactive or token-based) +- **Adaptive tests**: Automatically skips tests not applicable to target environment (e.g., cert tests on Azure) + +### Full Test Coverage + +The full test suite validates: +- Basic functionality (help, queries, connection modes) +- Prepared statements +- File parsing and GO batch separators +- Timeout handling (query and login) +- Parameter validation (all command-line options) +- TDS 8.0 encryption modes +- Connection-only testing +- Security validation +- Concurrency (100 threads, plus 500/1024 max threads) +- Error handling and SQL syntax errors +- Multi-result sets +- JSON output structure and validity (validates `-json` produces valid JSON, and `-v -json` includes verbose fields) +- **Output format validation** (validates 18 elements in non-verbose, 26 in verbose, 20 in JSON) +- **Terminology consistency** (verifies "batches" terminology used consistently, not "queries") +- **Example validation** (validates help text, documentation, and example script patterns work correctly) +- **Replay testing** (parameter conflicts, fast/stress mode, replay summary validation, JSON replay fields, verbose event output) +- Always Encrypted support detection +- **Performance regression tests** (3 scenarios, compared ±20% against a baseline saved on the same machine and SQL Server when one exists, otherwise fixed thresholds) +- Read-only routing and multi-subnet failover (requires `-TestReadReplica` flag) + +**Output Format Validation**: The test suite includes comprehensive validation of output formats: +- **Non-verbose output**: Validates 18 key elements including Server, Database, Authentication, batch counts, Performance Metric Summary, avg connect time, avg elapsed, time breakdown +- **Verbose output**: Validates 26 key elements including all 5 PHASE markers, connection metrics, avg elapsed time +- **JSON output**: Validates 33 key JSON fields including configuration (server, database, authentication, optional features), metrics, runtime breakdown +- **Terminology check**: Ensures "batches" is used consistently (not "queries") across all output modes + +**JSON Output Validation**: All tests that use `-json` validate the output is proper JSON using PowerShell's `ConvertFrom-Json`. The verbose JSON test (Test 35) additionally verifies that when `-v -json` are used together, the output includes the three verbose fields at top level: `connection_string`, `thread_connections`, and `thread_iterations`. + +**Performance Baselines**: The smoke test's performance checks use ratios and per-iteration slopes of `SELECT 1` runs, so process start, driver load, and login cost cancel out and no baseline is needed. The full suite compares its three scenarios against a baseline saved with `baseline/save-full-perf-baseline.ps1` (5 runs, median), but only when that baseline was recorded on the same machine, CPU, server, and SQL Server version; otherwise it uses fixed thresholds (5s, 10s, 30s). Baselines are machine-specific, so `baseline/*.json` is ignored by Git. Each test run saves a measurement to `measurements/` with machine config, SQL Server version, and optional `-PerfTag` annotation. + +## ODBC Debug Mode + +**⚠️ Performance Warning**: ODBC debug logging adds significant overhead and should **only be used for debugging**.

Add `-Preview` to list changes without writing, `-Force` to replace differing files, `-Architecture x64` or `-Architecture ARM64` to publish one architecture, and `-ReportPath <file>` for a JSON record of what changed. To build, install, validate, and get a receipt in one step, use `..\scripts\install-local.ps1` from the repository root. + +### Release Validation + +After publishing, validate the release package works correctly: + +```powershell +# Test against localhost/on-premises SQL Server +.\test-nonazure-release-examples.ps1 + +# Test with SQL Authentication (optional) +.\test-nonazure-release-examples.ps1 -SqlUser "myuser" # prompts for the password + +# Test against Azure SQL Database (requires Azure CLI) +.\test-azure-release-examples.ps1 -ServerName "myserver.database.windows.net" + +# Skip interactive auth prompt for automated testing +.\test-azure-release-examples.ps1 -ServerName "myserver.database.windows.net" -SkipInteractive +``` + +These scripts test the example scripts in the staged release (default `release/sqlsimtools/1.0/sqlsim/examples/`, or `-ReleaseDir`) to ensure they work correctly in the distributed package. + +### Pandoc Requirement + +The `publish.ps1` script requires **pandoc** to generate HTML documentation from `sqlsim.md`: + +**Install pandoc:** +```powershell +winget install pandoc +``` + +**Or download:** https://pandoc.org/installing.html + +After installation, pandoc will be available at: +- `C:\Users\<username>\AppData\Local\Pandoc\pandoc.exe` +- Or in PATH if installed system-wide + +**Note:** The publish script automatically detects pandoc in common locations. + +## Continuous Integration + +The repository runs a GitHub Actions workflow on every pull request that +touches `sqlsim/` (and on pushes to `main`). It lives at +`.github/workflows/sqlsim-ci.yml` and has two jobs: + +1. **Build (`windows-latest`, x64)** + - Runs `sqlsim/build.ps1 -Architecture x64 -Configuration Release` on a + clean Windows runner (same toolchain as a local build: cmake + MSBuild + + Visual Studio 2022 from the runner image). + - Verifies `sqlsim/build/x64/Release/sqlsim.exe` was produced. + - Runs offline sanity checks: `sqlsim.exe -h` and `sqlsim.exe -version` + must exit 0. + - Uploads the built `sqlsim.exe` as a workflow artifact (`sqlsim-x64-release`, + 14-day retention) so reviewers can grab the exact binary the PR produced. + +2. **PSScriptAnalyzer** + - Installs `PSScriptAnalyzer` and scans all PowerShell scripts in `sqlsim/` + (`build.ps1`, `smoke-test.ps1`, `publish.ps1`, examples, etc.). + - Fails the job on any **Error**-severity finding. Warnings are tolerated. + +**What is NOT run in CI:** `smoke-test.ps1` and `full-test-suite.ps1` require +a live SQL Server / Azure SQL endpoint, which is not available on hosted +runners. These remain manual gates before publishing a release — run them +locally with `-PerfTag pre-release` and review the results under +`measurements/`. + +**Triggering manually:** the workflow also supports `workflow_dispatch`, so +you can re-run it from the **Actions** tab without opening a PR. + +**Other tools' CI:** sqlpysim, sqlsim Studio, plugin validation, and the macOS +Private Preview each have their own workflow under `.github/workflows/`.

Every ODBC API call returns a result code, and when the result is not pure success, diagnostic records are available via `SQLGetDiagRecW`. sqlsim categorizes all diagnostic records into three tiers based on their SQLSTATE: + +**Three-Tier Diagnostic Classification:** + +| Tier | SQLSTATE | What It Means | Examples | +|---|---|---|---| +| **Errors** | Non-`01xxx` (42S02, 42000, HYT00, 08S01, etc.) | Something failed | "Invalid object name", "Query timeout expired", "Communication link failure" | +| **Informational messages** | `01000` | Routine messages from T-SQL execution | PRINT output, RAISERROR sev ≤ 10, DBCC output, SET STATISTICS output | +| **ODBC warnings** | `01001`, `01003`, `01004`, etc. (01xxx but NOT 01000) | Real ODBC-level warnings | "String data right-truncated", "Cursor operation conflict" | + +> **Note:** SQL Server ODBC Driver 18 sends virtually all informational and warning messages as SQLSTATE `01000`. The non-01000 warning states (01001, 01003, 01004) are defined in the ODBC spec but are rarely emitted by the SQL Server driver in practice. + +**Routine Server Messages (Filtered Out):** + +Certain `01000` messages are routine server housekeeping and are automatically filtered — they are never displayed: +- `Changed database context to '...'` (native error 5701) — sent on USE statements and initial connection +- `Changed language setting to ...` (native error 5703) — sent on SET LANGUAGE and initial connection + +**How Errors Are Handled:** + +| Error Source | Behavior | Format | +|---|---|---| +| **SQL Server query errors** | Displayed with SQLSTATE code; continues by default, or stops with `-stoponerror` | `SQLSTATE: [Driver][Provider]Error message` | +| **Connection failures** | ODBC driver prefix included; enhanced messages for missing driver (IM002) | Chained errors separated by ` \| ` | +| **Query timeouts (HYT00)** | Detected specially for timeout metrics; affected by `-t` parameter | `HYT00: Query timeout expired` | +| **Login timeouts (HYT00/HYT01)** | Affected by `-l` and `-retry` parameters | `HYT00: Login timeout expired` | +| **Missing ODBC driver (IM002)** | Pre-flight check before any connection; includes installation instructions | `sqlsim error: Microsoft ODBC Driver for SQL Server is not installed.` | +| **Parameter validation** | Checked before any connection attempt; immediate exit with code 1 | `sqlsim error: <message>` | +| **Fatal runtime errors** | Rare safety-net handlers for C++ exceptions | `sqlsim fatal error: <message>` | + +**Multi-Statement Batch Error Detection:** + +When a batch contains multiple statements (e.g., `PRINT 'x'; RAISERROR('err', 16, 1); SELECT 1`), errors from non-first statements are detected during result set processing via `SQLMoreResults`. These are counted as errors and affect exit code. + +**ODBC API Surface:** + +sqlsim uses the wide (Unicode) ODBC APIs throughout: `SQLExecDirectW`, `SQLGetDiagRecW`, `SQLPrepareW`, `SQLDescribeColW`, `SQLGetData` with `SQL_C_WCHAR`. All error messages and query text are converted between UTF-8 and UTF-16 for proper Unicode support. + +**Security:** + +All error messages are sanitized before display to prevent terminal control character injection. Messages are limited to 1000 characters. Connection string parameters reject metacharacters (`;`, `{`, `}`) to prevent injection. + +For detailed error handling documentation with examples, see [sqlsim.md](sqlsim.md#error-handling). + +## Publishing + +To publish the release build and generate HTML documentation: + +```powershell +.\publish.ps1 +``` + +This script: +- Builds and copies `sqlsim/x64/sqlsim.exe` and `sqlsim/ARM64/sqlsim.exe` +- Copies `sqlsim/sqlsim.md` (user manual) +- Converts `sqlsim.md` to HTML using pandoc +- Copies the `sqlsim/examples\` folder (sample scripts, SQL files, workloads, and reports in subfolders) +- Copies `.github/skills/sqlsim/SKILL.md` for agent discovery +- Copies `.github/agents/sqlsimtools-workload-builder.agent.md` for guided workload authoring, execution approval, result analysis, and A/B comparisons + +Default installation root: `<repo>\release\sqlsimtools\1.0` (relative to repo root) + +**Requirement:** Pandoc must be installed for HTML generation.

+.DESCRIPTION + Compares a baseline run against a candidate run and reports the measured + change in throughput, runtime, execution time, connection time, and errors. + + Accepts either two sqlsim or sqlpysim result files produced by -json, or a + single comparison bundle exported from the sqlsim Studio Compare view. + + The report includes a configuration guardrail. A performance delta between + two runs that used different targets, engines, workloads, load shapes, telemetry, + query-statistics settings, or execution options is not a result, and the + report says so rather than presenting a misleading number. ODBC driver and + SQL Server version differences are shown but do not block the comparison, + because they are often the change under test. + + Metrics match sqlsim Studio Compare: throughput uses execution elapsed time, + average execution uses total query time divided by executions, and Replay + uses the number of replayed events. + +.PARAMETER BaselineFile + Path to the baseline sqlsim JSON result file (the "A" run). + +.PARAMETER CandidateFile + Path to the candidate sqlsim JSON result file (the "B" run). + +.PARAMETER ComparisonFile + Path to a comparison bundle exported by sqlsim Studio.

suite for sqlsim +.DESCRIPTION + Runs smoke-test.ps1 first, then executes extended tests covering + connection modes, parameters, timeouts, file parsing, concurrency, error handling, + security validations, cursor state, T-SQL features, output formats, workload, and replay. +.PARAMETER SkipBuild + Skip the build step and use existing executable +.PARAMETER Verbose + Verbosity level for test output: + 0 (default) - Show test command being executed + 1 - Also pass -v to sqlsim for detailed sqlsim output +.PARAMETER Server + SQL Server name to test against (default: localhost) + Automatically detects Azure SQL Database if name contains 'database.windows.net' or 'database.fabric.microsoft.com' +.PARAMETER Database + Database name to test against (default: tempdb) +.PARAMETER UseToken + Access token for Azure SQL Database authentication (enables automated testing) + When provided, uses -T (access token) instead of -A (interactive login) + The token, like -Password, reaches sqlsim on stdin (-T -, -P -), so it never + appears in a process list. +.PARAMETER SkipScale + Skip the 1024 thread scale test (useful for testing against environments that cannot handle high concurrency) +.EXAMPLE + .\full-test-suite.ps1 + Run all tests against localhost with Windows Authentication +.EXAMPLE + .\full-test-suite.ps1 -Server "myserver.database.windows.net" -Database "mydb" + Run tests against Azure SQL Database (auto-detects Azure and uses Entra auth) +.EXAMPLE + .\full-test-suite.ps1 -Server "myserver.database.windows.net" -Database "mydb" -UseToken "ey..." + Run tests against Azure SQL Database using access token (automated, non-interactive) +.EXAMPLE + .\full-test-suite.ps1 -Server "192.168.1.100" -Database "testdb" + Run tests against a remote SQL Server with Windows Authentication +.EXAMPLE + .\full-test-suite.ps1 -OutputFile "test-results.log" + Run tests and log output to both console and file with timestamps +.EXAMPLE + .\full-test-suite.ps1 -StopOnError + Run tests and stop immediately on first failure +.EXAMPLE + .\full-test-suite.ps1 -SkipScale + Run all tests except the 1024 thread scale test +.PARAMETER TestReadReplica + Run tests for -R (read-only intent) and -M (multi-subnet failover) parameters. + Use this when testing against a server with read replicas (Azure SQL with replicas, AG listener, etc.) +.PARAMETER LoginTimeout + Login timeout in seconds for the 1024 thread scale tests (default: 60). + Use a higher value when testing against Azure SQL or slower environments. +#> + +param( + [switch]$SkipBuild, + [int]$Verbose

These are expected errors +during replay of traces that included bulk operations. + +**login/logout events show as "skipped"** — This is correct.

It enables simulation of multi-threaded workloads, connection stress testing, and performance measurement for SQL queries. sqlsim is ideal for database administrators, developers, and performance engineers who need to evaluate database performance or behavior under various load conditions. + +**⚠️ Important:** sqlsim is a **testing and workload simulation tool** designed for development, testing, and performance evaluation environments. It is **NOT intended for use against production systems**. Running sqlsim with high thread counts (`-n`) can consume substantial CPU, memory, network bandwidth, and database connections on the client and server. Excessive concurrency can make the client unresponsive, exhaust resources, and distort benchmark results before the database reaches its limit. Start with a small thread count, increase it gradually, and monitor both client and server resources. Use dedicated test environments and, for significant load tests, a dedicated client machine. + +**How This Tool Was Built:** +100% of the code, scripts, and documentation for sqlsim was developed with GitHub Copilot in Visual Studio Code using various AI models, but 100% orchestrated by Bob Ward. + +**Key Capabilities:** +- Single native application binary with no sqlsim installer or language runtime required +- Native builds for Windows x64/ARM64 and Ubuntu 24.04/26.04 LTS x64 +- Platform ODBC dependencies: ODBC Driver 18 on Windows; unixODBC and ODBC Driver 18 on Linux +- Execute single queries or SQL script files +- Multi-threaded workload simulation +- Multiple authentication methods (Windows, Entra, SQL Auth, Access Token) +- Prepared statement support +- Detailed performance metrics (connection time, query execution, fetch time) +- Timeout controls for connections and queries +- TDS 8.0 encryption support +- Connection behavior controls (reconnect, connection pooling) +- Support for read replicas and Always On Availability Groups +- XEvent trace replay (capture supported query events and replay their session order or load shape) +- Mixed workload simulation from JSON definition files (`-workload`) +- Per-query server statistics with SET STATISTICS TIME/IO (`-querystats`) +- Full Unicode support (UTF-8 input and output for international characters) +- Support for local SQL Server, Azure SQL Database, Azure SQL Managed Instance, Azure Synapse Analytics, and SQL database in Fabric, SQL analytics endpoint in Fabric, and Fabric Warehouse. + +**Top 10 Cool Things You Can Do with sqlsim:** + +| # | Cool Thing | Why It's Unique | +|---|------------|-----------------| +| **1** | **Stress test any SQL workload with 1000+ concurrent users on x64 or Windows ARM64 devices — or test connections only** | Just add `-n 1000`, `-r` for iterations, and `-q` to suppress results for max throughput to any ad-hoc query (`-Q`), input file (`-i`), or JSON workload definition (`-workload`) with full batch support. Omit `-Q` to test auth overhead and connection limits | +| **2** | **Replay production workloads from XEvent traces** | Capture Extended Events, convert with `convert-xel.ps1`, replay with `-replay fast` (per-session fidelity) or `-replay stress` (max throughput). Includes replay summary comparing original vs replay outcomes | +| **3** | **No sqlsim installer required** | One native application binary per platform: `sqlsim.exe` on Windows or `sqlsim` on Linux; platform ODBC components must be installed | +| **4** | **Test Azure SQL with modern Entra authentication** | Full Entra support (interactive, MSI, tokens) | +| **5** | **Connect to any SQL — ground to cloud to Fabric** | SQL Server (bare metal, VM, Linux, containers), Azure SQL Database, Azure SQL Managed Instance, Azure Synapse Analytics, SQL database in Fabric, and Fabric Warehouse | +| **6** | **Run mixed workloads from a single JSON definition** | Define OLTP, reporting, and monitoring groups with different thread counts and iterations in one `-workload` file — all threads launch concurrently | +| **7** | **Export results as JSON for monitoring/automation pipelines** | Machine-readable output for Grafana, Prometheus, CI/CD | +| **8** | **Get detailed performance metrics and per-query server statistics including HTML performance reports** | Average timing metrics for connections and queries, plus `-querystats` for SET STATISTICS TIME/IO aggregated across all threads — server CPU, elapsed time, logical reads, physical reads per unique query. Generate interactive HTML reports with Chart.js bar charts and click-to-navigate query detail | +| **9** | **Test retry and timeout behavior under load** | Verify your app's resilience patterns with `-retry` and `-retrydelay` | +| **10** | **Test advanced connection scenarios** | TDS 8.0 encryption (`-N`), AG read replicas (`-R`), multi-subnet failover (`-M`), connection pooling (`-usepool`), reconnect patterns (`-reconnect`) | + +[↑ Back to Table of Contents](#table-of-contents) + +## Installation + +### Prerequisites + +sqlsim ships as one native application binary per platform and has no application installer. It does not require the source tree or a language runtime. It is not fully static: Windows runtime connections require Microsoft ODBC Driver 18; Linux runtime connections require unixODBC and Microsoft ODBC Driver 18. These platform ODBC components are installed separately and are not bundled in the release archive. + +**Supported Platforms:** +- Windows x64 (Intel/AMD 64-bit processors) +- Windows ARM64 (Qualcomm Snapdragon, Microsoft SQ, Apple Silicon via Parallels) +- Ubuntu 24.04 and 26.04 LTS x64 + +Download the appropriate version for your platform: +- `sqlsim/x64/sqlsim.exe` - For standard Windows PCs and servers +- `sqlsim/ARM64/sqlsim.exe` - For Windows on ARM devices (Surface Pro X, Dev Kit 2023, etc.) +- `sqlsim/x64/sqlsim` - For Ubuntu x64 + +**Included Files:** +- `sqlsim/sqlsim.md` - Full documentation (this file) +- `sqlsim/sqlsim.html` - HTML version of documentation +- `sqlsim/AGENTS.md` - Instructions for coding agents (Copilot, Claude Code, Cursor, Aider, Codex CLI) that automatically tell them how to invoke sqlsim +- `sqlsim/LICENSE` - MIT license +- `.github/skills/sqlsim/SKILL.md` - VS Code Copilot skill descriptor (companion to `AGENTS.md`) +- `sqlsim/examples/` - Sample SQL scripts, PowerShell examples, workload definitions, and analysis scripts +- `sqlsim/replay/` - XEvent capture scripts, `convert-xel.ps1`, trace comparison, and the replay guide + +> **Note for ARM64 users:** The x64 version will run on Windows ARM64 devices via emulation, but the native ARM64 build provides better performance and lower power consumption.

Other Linux distributions may work when they provide compatible system libraries, unixODBC, and Microsoft ODBC Driver 18 packages, but they are currently untested and unsupported. Linux ARM64 is not currently supported. + +The release archive contains the native Linux executable `x64/sqlsim`; Linux executables do not use the Windows `.exe` extension. The binary needs no sqlsim installation or language runtime, but it is dynamically linked rather than fully static. unixODBC and Microsoft ODBC Driver 18 for SQL Server must be installed on the target system and are not bundled in the archive. The Linux build uses the same workload engine and command-line implementation as Windows. macOS ARM64 is available only through an invitation-only Private Preview for customers and testers helping validate the platform. + +### macOS ARM64 Private Preview + +A native Apple Silicon build is available to Private Preview participants through the manually triggered `sqlsim macOS ARM64 Private Preview` GitHub Actions workflow. It builds on the `macos-15` ARM64 runner, verifies the Mach-O architecture, runs offline smoke checks, and uploads a `sqlsim-macos-arm64-private-preview` artifact. This artifact is not part of the public sqlsim release. Customer and tester feedback will help complete native live connection validation and inform the signing and notarization decision. + +On an Apple Silicon Mac, the equivalent local commands are: + +```bash +brew install cmake unixodbc +bash ./build-macos.sh --clean +bash ./smoke-test-macos.sh --skip-build +``` + +Live database connections also require Microsoft ODBC Driver 18 for SQL Server, installed separately through Microsoft's Homebrew tap. + +### Build and Runtime + +```bash +# Build prerequisites +sudo apt-get update +sudo apt-get install -y build-essential cmake unixodbc-dev + +# Verify, build, and run offline tests +bash ./check-prerequisites-linux.sh +bash ./build-linux.sh --clean +bash ./smoke-test-linux.sh --skip-build + +# Verify the runtime driver before a live test +bash ./check-prerequisites-linux.sh --require-driver +``` + +Install `msodbcsql18` from Microsoft's package repository before making a database connection. Source builds produce `build/linux-x64/sqlsim`; release archives contain `x64/sqlsim`. + +### Feature Support + +| Feature | Linux status | Notes | +|---------|--------------|-------| +| Queries, scripts, workload JSON, and replay | Supported | Uses the shared cross-platform workload engine. XEvent files must first be converted to replay XML. | +| Multithreading (`-n`, `-r`) | Supported | Uses C++ `std::thread` with pthreads on Linux. | +| Prepared statements, reconnect, retries, and timeouts | Supported | Implemented through portable C++ and ODBC APIs. | +| Text/JSON output, `-o`, and query stats | Supported | Uses portable file and JSON paths; Linux query-stats snapshot replacement is not atomic across the remove/rename interval. | +| TDS 8.0 encryption and certificate options | Supported | Requires a compatible ODBC Driver 18 release. | +| Ctrl+C / SIGTERM termination | Supported | Exits immediately with conventional signal-derived status (`130` for SIGINT), matching the Windows immediate-termination behavior. | +| Connection pooling (`-usepool`) | Driver-manager dependent | Available through unixODBC; validate performance and reuse behavior in the target environment. | +| Windows-only HTML/report helper scripts | Not native to Linux | The sqlsim binary still produces the underlying text and JSON data. Run PowerShell helpers with `pwsh` where applicable. | + +### Authentication on Linux + +| sqlsim option | Linux status | Requirements | +|---------------|--------------|--------------| +| `-U <user> -P <password>` | Supported | SQL Server authentication must be enabled on the target. | +| `-T <token>` | Supported | Obtain a database access token externally, for example with Azure CLI, then pass it to sqlsim. | +| `-E` | Supported with Kerberos | A valid Kerberos ticket must already exist (`kinit`/`klist`). Driver 18 on Linux does not fall back to NTLM. | +| `-A ActiveDirectoryIntegrated` | Supported with Kerberos | ODBC Driver 17.6+ supports this mode on Linux; sqlsim requires Driver 18. A suitable Kerberos ticket is required. | +| `-A ActiveDirectoryMsi` | Supported in compatible Azure hosts | System-assigned identity needs no `-U`; user-assigned identity uses `-U <identity-guid>`. Driver 18.3+ also supports Azure Arc and Cloud Shell. | +| `-A ActiveDirectoryServicePrincipal -U <client_id> -P <client_secret>` | Supported | ODBC Driver 17.7+ supports this mode; sqlsim requires Driver 18. The client secret is visible to local process inspection when supplied on the command line. | +| `-A` or `-A ActiveDirectoryInteractive` | **Not supported** | Microsoft ODBC Driver interactive authentication is Windows-only. sqlsim rejects this mode on Linux with a targeted error. Use `-T` for an interactive workstation login. | +| Conditional Access requiring Windows WAM | **Not supported** | WAM is Windows-only. Acquire a compliant token outside sqlsim and use `-T` when permitted by policy. | + +Examples: + +```bash +# Token authentication (recommended for an interactive Linux workstation) +token="$(az account get-access-token --resource https://database.windows.net/ --query accessToken -o tsv)" +printf '%s\n' "$token" | ./x64/sqlsim -S myserver.database.windows.net -d mydb -T - -Q "SELECT 1" + +# Kerberos integrated authentication +kinit user@CONTOSO.COM +./x64/sqlsim -S sqlserver.contoso.com -E -Q "SELECT SUSER_SNAME()" + +# Managed identity on a compatible Azure host +./x64/sqlsim -S myserver.database.windows.net -d mydb -A ActiveDirectoryMsi -Q "SELECT 1" + +# Service principal: the client secret is read from stdin, not the command line +printf '%s\n' "$client_secret" | ./x64/sqlsim -S myserver.database.windows.net -d mydb \ + -A ActiveDirectoryServicePrincipal -U "$client_id" -P - -Q "SELECT 1" +``` + +The Linux smoke suite always runs offline CLI, authentication-validation, and signal tests. To add live tests, pass `--server`, `--database`, and either `--token-file` or `--username` plus `--password-file`. The suite reads only the first line of a secret file and passes the secret to sqlsim on stdin. CI can instead set `SQLSIM_SERVER`, `SQLSIM_DATABASE`, and either `SQLSIM_ACCESS_TOKEN` or `SQLSIM_USERNAME` plus `SQLSIM_PASSWORD`. + +[↑ Back to Table of Contents](#table-of-contents) + +## Getting Started + +### Running sqlsim + +**Note:** The examples in this documentation use `sqlsim.exe` assuming it's either in your PATH or you're running it from the sqlsim directory. + +**Options for running sqlsim:** +- **Add to PATH:** Add the sqlsim directory to your system PATH to run from anywhere +- **Run locally:** Navigate to the sqlsim directory and run `sqlsim.exe` (works in both PowerShell and Command Prompt) +- **Full path:** Use the full path like `C:\path\to\sqlsim.exe` + +> **Platform Note:** All examples work in both PowerShell and Windows Command Prompt (cmd.exe). + +### Minimum Required Parameters + +**Note:** Parameters which support values can be specified with or without a space (e.g., `-n 10` or `-n10`).

This provides performance benefits for repeated queries through query plan caching and reduced parsing overhead on the server side. + +**How it works:** +- **First execution**: Query is prepared once with `SQLPrepare()` and cached per connection +- **Subsequent executions**: Cached prepared statement is reused with `SQLExecute()` +- **With `-r` (iterations)**: Prepare once, execute many - ideal for performance testing +- **With `-reconnect`**: Statement cache is cleared on disconnect, requiring re-preparation after reconnect + +**Important:** sqlsim's prepared statement mode does NOT use parameter binding with markers (e.g., `?` placeholders). Queries are still executed with their full text. The `-p` flag is useful for: +- **Performance testing**: Measure the impact of query plan caching with `-r` iterations +- **Repeated queries**: Reduce parsing overhead when executing the same query multiple times +- **Server-side optimization**: Leverage SQL Server's prepared statement handling + +**What it does NOT provide:** +- Parameter value binding (no `SQLBindParameter()` usage) +- Parameter marker support (e.g., `?` placeholders in queries) + +Note: SQL injection is not a concern for sqlsim since it executes user-provided query text directly without any input substitution. + +For true parameterized queries with bound values, you would need to modify your queries to use parameter markers and extend sqlsim to support parameter binding. + +### Security & Encryption Options + +| Parameter | Description | Default | Example | +|-----------|-------------|---------|---------| +| `-N [level]` | TDS 8.0 encryption: o (optional), m (mandatory), s (strict) | m | `-N s` | +| `-C` | Trust server certificate (bypass validation) | off | `-C` | +| `-F <hostname>` | Expected certificate hostname for validation | - | `-F sql.company.com` | + +#### Certificate validation + +sqlsim follows the same negotiation rule as `sqlcmd` (Go): + +| Options | Certificate validation | +|---------|------------------------| +| Neither `-N` nor `-C` | Not validated | +| `-N` without `-C` | Required | +| `-C` | Bypassed | + +So a bare `sqlsim -S localhost -E` connects to a server with a self-signed +certificate, while `-N m` against the same server fails until you supply `-C` +or install a trusted certificate. `-F` overrides the name the certificate is +checked against, for a server reached by an IP address, a DNS alias, or an +availability-group listener; it cannot be combined with `-C`, which would make +the check meaningless. + +This rule applies to every authentication mode, including `-T`, which matters +most on the Azure SQL path: Azure presents a certificate from a trusted +authority, and the connection crosses the internet. Use `-N s` or `-N m` with +`-T` to validate; `-T` alone connects without validating. + +Note that `sqlcmd` (ODBC) 18 and later are stricter than this: they validate by +default, so a bare connection to a self-signed server fails there but succeeds +with sqlsim. + +### High Availability Options + +| Parameter | Description | Default | Example | +|-----------|-------------|---------|---------| +| `-R` | Read-only intent (route to AG secondary replica) | false | `-R` | +| `-M` | Multi-subnet failover (faster AG failover) | false | `-M` | + +### Error Handling Options + +| Parameter | Description | Default | +|-----------|-------------|---------| +| `-stoponerror` | Stop on first error | false (continue) | +| `-retry <count>` | Connection retry attempts (0-255) | 1 | +| `-retrydelay <seconds>` | Delay between retries (1-60 seconds) | 10 | + +### Replay Options + +| Parameter | Description | Default | +|-----------|-------------|---------| +| `-replay <mode>` | Replay mode: `fast` (session-ordered, as-fast-as-possible replay) or `stress` (flattened workload for max throughput) | - | +| `-replayfile <xmlfile>` | XML replay file generated by `convert-xel.ps1` from XEvent `.xel` traces | - | + +**Notes:** +- `-replay` and `-replayfile` are mutually exclusive with `-Q`, `-i`, and `-workload` +- **Fast mode**: One thread per original session, with supported events replayed as fast as possible in captured order using the corresponding ODBC methods +- **Stress mode**: Flattened event list distributed across `-n` threads for maximum throughput testing +- Both modes output a **replay summary** comparing original trace outcomes (ok/error/abort) vs replay outcomes +- Database context switching is automatic — each event executes in its original database context + +### Output Options + +| Parameter | Description | Default | +|-----------|-------------|---------| +| `-o <outputfile>` | Write all output to file including errors (like sqlcmd -o) | - | +| `-q` | Quiet mode (suppress query results) | false | +| `-v` | Verbose mode (detailed phases, metrics, and command line echo) | false | +| `-querystats` | Show per-query server stats (SET STATISTICS TIME/IO aggregated across all threads) | false | +| `-querystats-interval <seconds>` | Write a query-statistics snapshot to a file every n seconds while the run is in progress (implies `-querystats`) | off | +| `-querystats-file <file>` | Snapshot path used by `-querystats-interval` | querystats-live.json | +| `-json` | Output canonical JSON; combine with `-stream-json -o <file>` to retain a final result while streaming | false | +| `-stream-json` | Stream newline-delimited JSON progress events once per second | false | +| `-h`, `-?`, `--help` | Show help message | +| `--version` | Show version information | + +> **Note:** All output lines (except JSON mode) are automatically prefixed with timestamps in `YYYY-MM-DD HH:MM:SS.mmm | ` format for millisecond-precision timing. + +`-querystats-interval` writes a first snapshot immediately, then one per +interval, then a final snapshot marked `complete` after the last thread +finishes. Each file is written to a temporary name in the same directory and +renamed over the target, so a reader polling the file never sees a partially +written document. + +A snapshot write failure never interrupts the workload: the run continues and +the exit code is unchanged. The first failure is reported once on stderr so a +mistyped path does not leave the run looking healthy, and later failures stay +quiet so the interval timer cannot flood the output. The message is suppressed +in `-json` and `-stream-json` modes, where it would corrupt the channel a +supervising process is parsing; in those modes, check whether the file exists. +`sqlpysim` behaves identically. + +See [Understanding Output](#understanding-output) section for detailed information on output modes, JSON structure, and data extraction. + +### Parameter Format + +Parameters can be specified in two ways: + +**Space-separated (traditional):** +```powershell +sqlsim.exe -S localhost -d master -n 10 -r 100 +``` + +> **Note on Parameter Quoting:** Unlike some SQL Server tools (like `ostress.exe`), sqlsim does NOT require quotes around parameter values unless they contain spaces or special characters. Simple values like server names, database names, and queries can be specified without quotes. For example: `-S localhost -d testdb -Q "SELECT 1"` is valid, and the quotes around `SELECT 1` are only needed because the query contains a space. + +**Concatenated (no space):** +```powershell +sqlsim.exe -Slocalhost -dmaster -n10 -r100 +``` + +Both styles work identically. You can mix both styles in the same command. + +> **PowerShell Compatibility:** sqlsim automatically handles PowerShell's dot-splitting behavior. When PowerShell splits arguments like `-Sserver.domain.com` or `-ifile.sql` at the dot, sqlsim reassembles them correctly. Both concatenated and space-separated styles work reliably for all parameters. + +### Platform & Version Requirements + +Some parameters require specific SQL Server versions or Azure platforms: + +| Parameter | Platform Requirements | +|-----------|----------------------| +| `-E` | SQL Server (Windows), SQL Server on Linux with AD integration | +| `-A` | Azure SQL Database, Azure SQL MI, Fabric SQL Database, SQL Server 2022+ with Entra auth | +| `-T` | Azure SQL Database, Azure SQL MI, Fabric SQL Database | +| `-N s` (strict) | SQL Server 2022+, Azure SQL (TDS 8.0 required) | +| `-N m` (mandatory) | SQL Server 2012+, Azure SQL | +| `-N o` (optional) | All SQL Server versions | +| `-R` | SQL Server AG with readable secondary, Azure SQL Business Critical/Premium | +| `-M` | SQL Server AG with multi-subnet configuration, Azure SQL | + +**Notes:** +- All parameters work with Azure SQL Database, Azure SQL MI, and Fabric unless otherwise specified +- TDS 8.0 strict encryption (`-N s`) requires SQL Server 2022 or later, or any Azure SQL service +- Microsoft Entra authentication (`-A`) is available on Azure SQL Database, Managed Instance, SQL Server 2022+ (with Azure Arc), and SQL database in Fabric +- Windows Authentication (`-E`) is not supported on Azure SQL Database (use `-A`, `-T`, or SQL auth) + +### Parameter Conflicts + +Certain parameter combinations are mutually exclusive. sqlsim validates these at startup and reports clear error messages: + +| Conflict | Error Message | +|----------|---------------| +| `-Q` with `-i` | "Cannot use -Q with -i (choose one query source)" | +| `-T` with `-E`, `-A`, or `-U/-P` | "Cannot use -T (access token) with -E, -A, or -U/-P options" | +| `-F` with `-C` | "Cannot use -F (certificate hostname) with -C (trust server certificate)" | +| `-usepool` without `-reconnect` | "-usepool requires -reconnect (connection pooling only applies when reconnecting)" | +| `-c` with `-S`, `-d`, `-E`, `-U`, `-P` | "Cannot use both -c and -S/-d/-E/-U/-P options" | +| No authentication specified | "Must specify either -E (Windows Auth), -A (Entra), -T (Access Token), or -U (SQL Auth)" | +| `-replay`/`-replayfile` with `-Q` or `-i` | "Cannot use -replay with -Q or -i (queries come from replay file)" | +| `-replay` with `-workload` | "Cannot use -replay with -workload (choose one mode)" | +| `-workload` with `-Q` or `-i` | "Cannot use -workload with -Q or -i (queries come from workload file)" | +| `-workload` with `-replay` | "Cannot use -workload with -replay (choose one mode)" | +| `-p` with `-replay` | "Cannot use -p with -replay (replay uses its own ODBC methods per event type)" | +| `-reconnect` with `-replay` | "Cannot use -reconnect with -replay (replay manages its own connections)" | +| `-usepool` with `-replay` | "Cannot use -usepool with -replay (replay manages its own connections)" | +| `-n` with `-replay fast` | Warning: thread count is ignored in fast mode (determined by session count) | + +**Note:** `-Q`, `-i`, `-workload`, and `-replay` are mutually exclusive query sources.

A parser maximum is not a recommended operating +size. + +### Enforced Limits + +| Item | Limit | Behavior | +|------|-------|----------| +| Command-line query (`-Q`) | 1,048,576 bytes (1 MiB) | sqlsim rejects a larger value. Use `-i` for large scripts. | +| Replay XML file (`-replayfile`) | 100 MiB | sqlsim rejects a larger file before parsing it. | +| Replay events | 100,000 events | sqlsim rejects replay XML containing more events. | +| Replay XML nesting | 64 levels | sqlsim rejects more deeply nested XML. | +| Input and replay file paths | 4,096 characters | The operating system may impose a lower practical path limit. | +| Command-line threads (`-n`) | 1 to 2,147,483,647 | This is a parser range, not a safe or practical thread count. | +| Command-line iterations (`-r`) | 1 to 2,147,483,647 | Total executions multiply by threads and batches. | +| Displayed column value | 1,048,576 wide characters | Larger values are truncated and marked with a warning in result output. | + +Replay limits apply only to sqlsim; sqlpysim does not support replay. + +### Memory-, Disk-, and Server-Dependent Limits + +| Item | sqlsim limit | Resource consideration | +|------|--------------|------------------------| +| SQL script (`-i`) | No explicit file-size cap | The complete file is loaded into memory and split into batches before execution. | +| Workload JSON (`-workload`) | No explicit file-size cap | The complete JSON document is loaded into memory before parsing. | +| Script referenced by workload JSON | No explicit file-size cap | Each script is loaded into memory; workload expansion and high thread counts increase client memory use. | +| Inline query in workload JSON | No explicit per-query cap | Query text is held in memory and remains subject to SQL Server's batch limit. | +| Text, JSON, and statistics output files | No explicit file-size cap | Available disk space is the effective limit. Verbose output and large error collections can grow quickly. | +| SQL batch sent to the server | SQL Server limit | SQL Server allows 65,536 times the negotiated network packet size per batch; the default 4 KB packet size is approximately 256 MiB. | + +Use `GO` separators to split large scripts into smaller batches. Keep individual +batches well below the server maximum; very large batches increase client +memory, network traffic, compilation cost, and server memory use. + +### Concurrency Is Resource-Bound + +The numeric range accepted by `-n` is not a tested concurrency ceiling. Each +worker consumes client memory, scheduling capacity, network resources, and a +database connection. Workload-file groups add their thread counts together. +Start with a small thread count, scale gradually, and monitor CPU, memory, +network, open connections, and errors on both client and server. Stop scaling +when the client becomes saturated, because results beyond that point measure +the load generator rather than the database. Use a dedicated client machine +for significant load tests. + +[↑ Back to Table of Contents](#table-of-contents) + +## Usage Examples + +The following examples demonstrate common sqlsim scenarios organized by category. + +### Basic Query Execution + +**Simple query test:** +```powershell +# Execute a single query +sqlsim.exe -S localhost -d master -E -Q "SELECT @@VERSION" +``` + +**Default to localhost (matches sqlcmd behavior):** +```powershell +# -S defaults to localhost when authentication is provided +sqlsim.exe -E -Q "SELECT @@VERSION" + +# Works with database specification +sqlsim.exe -d testdb -E -Q "SELECT @@SERVERNAME" +``` + +**Named instance connection:** +```powershell +# Connect to a named SQL Server instance +sqlsim.exe -S localhost\SQLEXPRESS -d testdb -E -Q "SELECT @@SERVERNAME" + +# Connect to named instance with custom port +sqlsim.exe -S myserver\INSTANCE,1434 -d testdb -E -Q "SELECT @@VERSION" +``` + +**Query from file:** +```powershell +# Execute queries from a SQL script file +sqlsim.exe -S localhost -d testdb -E -i workload.sql +``` + +**Custom ODBC connection string:** +```powershell +# Full control over ODBC connection parameters +sqlsim.exe -c "Driver={ODBC Driver 18 for SQL Server};Server=localhost;Database=master;Trusted_Connection=yes;Encrypt=Mandatory;TrustServerCertificate=Yes;" -Q "SELECT @@VERSION" +``` + +**Prepared statements for better performance:** +```powershell +# Use prepared statements with repeated queries +sqlsim.exe -S localhost -d testdb -E -Q "SELECT * FROM Users WHERE ID = 1" -p -n 10 -r 1000 +``` + +**Verbose mode for debugging:** +```powershell +# See detailed execution phases and metrics +sqlsim.exe -S localhost -d testdb -E -Q "SELECT 1" -v +``` + +**Quiet mode for load testing:** +```powershell +# Suppress result output, show only metrics +sqlsim.exe -S localhost -d testdb -E -i queries.sql -n 50 -r 100 -q +``` + +**Output file redirection:** +```powershell +# Write all output to file (like sqlcmd -o) +sqlsim.exe -S localhost -d testdb -E -Q "SELECT @@VERSION" -o output.txt + +# Capture load test results to file +sqlsim.exe -S localhost -E -i queries.sql -n 10 -r 100 -o results.txt + +# Run multiple instances without output collision +sqlsim.exe -S localhost -E -i workload1.sql -n 5 -r 50 -o test1.txt +sqlsim.exe -S localhost -E -i workload2.sql -n 5 -r 50 -o test2.txt +``` + +**JSON output for programmatic parsing:** +```powershell +# Output results in JSON format +sqlsim.exe -S localhost -d testdb -E -Q "SELECT @@VERSION" -json + +# Save JSON results to file for parsing +sqlsim.exe -S localhost -E -Q "SELECT 1" -n 10 -r 100 -json -o results.json + +# Parse JSON with PowerShell +sqlsim.exe -E -Q "SELECT 1" -n 5 -r 2 -json | ConvertFrom-Json | Select-Object version, success + +# Extract specific metrics from verbose JSON (query_execution_operations requires -v) +$result = sqlsim.exe -E -Q "SELECT 1" -n 10 -json -v | ConvertFrom-Json +Write-Host "Total Queries: $($result.metrics.query_execution_operations.total)" +Write-Host "Avg Elapsed: $($result.metrics.query_execution_operations.avg_elapsed_ms) ms" +Write-Host "Success: $($result.success)" +``` + +**Stop on first error:** +```powershell +# Exit immediately on any SQL error +sqlsim.exe -S localhost -E -i script.sql -stoponerror +``` + +**Query and login timeouts:** +```powershell +# Set 30-second connection timeout and 60-second query timeout +sqlsim.exe -S myserver -d mydb -E -l 30 -t 60 -i workload.sql +``` + +**Timeout behavior:** + +When a timeout occurs, sqlsim displays the ODBC error with timestamp: + +**Login Timeout:** +``` +2026-01-18 10:30:45.123 | HYT00: [Microsoft][ODBC Driver 18 for SQL Server]Login timeout expired +``` +Indicates connection could not be established within the specified time (`-l` parameter).

This is ideal for simulating realistic database activity where OLTP queries, reporting queries, and monitoring queries all run simultaneously. + +### Workload JSON Format + +A workload definition is a JSON file with an array of workload groups and optional top-level settings: + +```json +{ + "workloads": [ + { + "file": "examples\\sql\\01-simple-queries.sql", + "threads": 2, + "iterations": 3 + }, + { + "queries": [ + "SELECT DB_NAME() AS DatabaseName, GETDATE() AS CheckTime", + "SELECT COUNT(*) AS SessionCount FROM sys.dm_exec_sessions WHERE is_user_process = 1" + ], + "threads": 1, + "iterations": 5 + } + ] +} +``` + +**Workload Group Fields:** + +| Field | Type | Required | Description | +|-------|------|----------|-------------| +| `file` | string | One of `file` or `queries` | Path to a SQL script file (relative to current directory).

Ignored when `duration_seconds` > 0. | +| `think_time_ms` | number | No | Delay in milliseconds between iterations (0 = tight loop, default). Simulates application-tier think time. | + +**Top-Level Settings:** + +| Field | Type | Required | Description | +|-------|------|----------|-------------| +| `workloads` | array | Yes | Array of workload group definitions (see above) | +| `duration_seconds` | number | No | Run each thread for this many seconds instead of a fixed iteration count. When set, `iterations` is ignored. | + +**Rules:** +- Each group must specify either `file` or `queries` (not both) +- The `file` path is relative to the current working directory (not relative to the JSON file) +- Comments (`//`) are supported in the JSON file +- The total thread count is the sum of all group thread counts +- All threads from all groups launch concurrently + +### Duration Mode + +Instead of running a fixed number of iterations, you can run each workload for a fixed duration using the top-level `duration_seconds` setting. This is useful for capacity testing where you want to measure throughput (queries/sec, business transactions/sec) at a given concurrency level. + +```json +{ + "duration_seconds": 60, + "workloads": [ + { + "file": "oltp_workload.sql", + "threads": 100 + }, + { + "queries": ["SELECT COUNT(*) FROM sys.dm_exec_sessions WHERE is_user_process = 1"], + "threads": 1 + } + ] +} +``` + +When `duration_seconds` is set: +- Each thread loops continuously until the deadline is reached +- The `iterations` field in each workload group is ignored +- All threads share the same deadline (they start and stop together) +- The configuration output shows "Duration: 60 seconds" instead of "Total batches to execute" +- Completed iteration count is reported per-thread in the metrics + +**Clean shutdown behavior:** When the deadline is reached, the currently executing query and iteration complete fully — no queries are interrupted mid-flight. The thread simply does not start a new iteration. This means every counted iteration represents a complete unit of work (e.g., a full stored procedure execution / business transaction), which is important for accurate throughput measurement. + +This enables demo scenarios like: "Run 100 OLTP users for 60 seconds at 128 vCores, then run 200 users for 60 seconds at 192 vCores" — comparing throughput between configurations. + +### Think Time + +Each workload group can specify a `think_time_ms` delay between iterations. This simulates the real-world pause between transactions — the time an application or user spends processing results, rendering UI, or waiting before issuing the next request. + +```json +{ + "duration_seconds": 60, + "workloads": [ + { + "file": "website_eligibility.sql", + "threads": 690, + "think_time_ms": 10 + }, + { + "file": "loan_application.sql", + "threads": 153, + "think_time_ms": 10 + }, + { + "file": "internal_report.sql", + "threads": 14, + "think_time_ms": 50 + } + ] +} +``` + +When `think_time_ms` is set: +- Each thread sleeps for the specified duration after completing an iteration, before starting the next one +- The sleep occurs **after** iteration metrics are recorded — think time is not included in query elapsed measurements +- Think time is per-workload-group, so website-facing queries can have short think times while batch/internal queries have longer ones +- With think time, more threads are needed to achieve the same instantaneous concurrency (threads × duty_cycle = effective concurrency) +- The configuration output shows `think=10ms` next to the group when non-zero + +**Why use think time:** Without think time, every thread runs in a tight loop — all 600 threads are always executing simultaneously. In production, users pause between requests. Think time creates realistic staggering: with 10ms think time and 12ms query time, each thread is active ~55% of the time. To maintain the same load, increase thread counts proportionally (e.g., 600 threads × 1/0.55 ≈ 1100 threads). This reduces instantaneous contention on shared resources (log writer, latches) and produces more realistic scaling behavior. + +### Workload Configuration Output + +When using `-workload`, the configuration display shows group details: + +``` +Configuration: +Server: localhost +Database: master +Authentication: Windows +Threads: 3 +Workload file: examples\workload\workload-test.json +Total batches to execute: 52 +Workload groups: 2 + Group 1: 2 thread(s), 3 iteration(s), 7 batch(es) [examples\sql\01-simple-queries.sql] + Group 2: 1 thread(s), 5 iteration(s), 2 batch(es) +``` + +In duration mode, the output changes to: +``` +Configuration: +Server: myserver.database.windows.net +Database: ZavaLendingDB +Authentication: Entra +Threads: 101 +Workload file: oltp-capacity-test.json +Duration: 60 seconds +Workload groups: 2 + Group 1: 100 thread(s), duration mode, 3 batch(es) [oltp_workload.sql] + Group 2: 1 thread(s), duration mode, 1 batch(es) +``` + +With think time enabled: +``` + Group 1: 100 thread(s), duration mode, 3 batch(es), think=10ms [oltp_workload.sql] + Group 2: 1 thread(s), duration mode, 1 batch(es) +``` + +### Example: Mixed Workload + +```powershell +# Run a mixed workload with query stats +sqlsim.exe -S localhost -E -d testdb -workload workload.json -querystats -q + +# Run with verbose output +sqlsim.exe -S localhost -E -workload examples\workload\workload-test.json -v +``` + +Create a workload file (`workload.json`): +```json +{ + // OLTP-style lightweight queries + "workloads": [ + { + "file": "examples\\sql\\01-simple-queries.sql", + "threads": 4, + "iterations": 100 + }, + { + // Inline monitoring queries + "queries": [ + "SELECT DB_NAME() AS DatabaseName, GETDATE() AS CheckTime", + "SELECT COUNT(*) AS SessionCount FROM sys.dm_exec_sessions WHERE is_user_process = 1" + ], + "threads": 1, + "iterations": 50 + } + ] +} +``` + +**Included Example Files:** +- `examples/workload/workload-test.json` — Two-group workload using system catalog queries (works on any database) +- `examples/workload/workload-example-adventureworkslt.json` — Three-group mixed workload with OLTP, reporting, and monitoring (requires AdventureWorksLT) + +### Thread Assignment + +Threads are assigned sequentially from the workload groups.

Throughput uses execution elapsed time, average execution uses total query execution time divided by executions, and Replay uses replayed events as its execution count. Average connection time is shown, but counts toward the verdict only when both runs use `-reconnect`. + +**Why the configuration comparison matters:** a throughput or timing difference between two runs that used different targets, engines, workloads, load shapes, query-statistics settings, or execution options is not a result. When any of those differ, the report reports **Not comparable** and names the differing settings rather than presenting a misleading verdict. ODBC driver, SQL Server version, and SQL Server edition differences are shown as informational because they are often the change under test. + +**Usage:** + +```powershell +# Compare two runs +.\examples\reports\comparison-report.ps1 -BaselineFile before.json -CandidateFile after.json + +# Label the runs and also emit CSV for a spreadsheet or CI +.\examples\reports\comparison-report.ps1 -BaselineFile sql2022.json -CandidateFile sql2025.json ` + -LabelA "SQL 2022" -LabelB "SQL 2025" -Csv upgrade.csv + +# Render a comparison exported from the sqlsim Studio Compare view +.\examples\reports\comparison-report.ps1 -ComparisonFile sqlsim-comparison-20260925.json + +# Widen the noise threshold for short runs where variance is high +.\examples\reports\comparison-report.ps1 -BaselineFile a.json -CandidateFile b.json -Threshold 10 +``` + +**Replay A/B testing:** the same report compares two replay runs.

Supported events replay as fast as possible in the order they occurred within each session, using the corresponding ODBC methods (prepared statements, parameterized queries, stored procedures). Captured timestamp gaps are not reproduced: + +```powershell +sqlsim -S localhost -E -replay fast -replayfile trace.xml +``` + +**Stress mode** (maximum throughput): + +All events are flattened into a single sequence and distributed across `-n` threads for maximum load generation: + +```powershell +sqlsim -S localhost -E -replay stress -replayfile trace.xml -n 8 -r 100 +``` + +### Replay Summary + +After replay completes, sqlsim displays a **replay summary** comparing the original trace event outcomes with the replay outcomes: + +``` +Replay Summary: + Original trace: 8 events (7 ok, 1 error, 0 abort) + Replay result: 8 events (8 ok, 0 error, 0 abort) +``` + +This shows at a glance: +- **Original trace**: How events completed when originally captured (ok, error, or abort/timeout) +- **Replay result**: How events completed during replay + +This is valuable for identifying: +- Queries that failed in production but succeed in test (or vice versa) +- Timeout differences between environments +- Overall workload health comparison + +**JSON replay summary** (`-json` flag): + +```json +{ + "replay_summary": { + "original": { + "events": 8, + "ok": 7, + "error": 1, + "abort": 0 + }, + "result": { + "events": 8, + "ok": 8, + "error": 0, + "abort": 0 + } + } +} +``` + +### Replay Options Reference + +#### Connection Requirements + +XEvent traces capture SQL text, parameters, database context, and session IDs — but **not** connection credentials or server addresses. You must always supply connection information when replaying: + +```powershell +# You must specify server + authentication (same as any sqlsim command) +sqlsim -S <server> -E -replay fast -replayfile trace.xml # Windows Auth +sqlsim -S <server> -A -replay fast -replayfile trace.xml # Entra Interactive +$password | sqlsim -S <server> -U user -P - -replay fast -replayfile trace.xml # SQL Auth (password on stdin) +``` + +This is actually a powerful feature — you can **replay a production trace against a different server**: + +```powershell +# Captured from production, replayed to test environment +sqlsim -S test-server.database.windows.net -d testdb -A -replay fast -replayfile prod-trace.xml +``` + +#### Compatible Parameters + +The following parameters work with replay mode: + +| Parameter | Behavior in Replay Mode | +|-----------|------------------------| +| `-S <server>` | **Required.** Target server for replay (can differ from original capture server) | +| `-d <database>` | Initial database. Each event auto-switches to its captured database context via `USE [database]`, so this is only used for the initial connection | +| `-E`, `-A`, `-T`, `-U`/`-P` | **Required.** Authentication for the target server (independent of how the original workload authenticated) | +| `-t <seconds>` | Query timeout applied to all replay events. Timeouts show as "abort" in the replay summary | +| `-n <threads>` | Thread count — **stress mode only**. In fast mode, thread count is determined by session count (specifying `-n` produces a warning) | +| `-r <iterations>` | Repeat the entire replay N times per thread | +| `-v` | Verbose — shows each event as it replays with event type and SQL preview | +| `-q` | Quiet — suppresses query result output during replay | +| `-json` | JSON output including `replay_summary` section | +| `-o <file>` | Write all output to file | +| `-stoponerror` | Stop on first replay error | +| `-app <name>` | Application name for the replay connections (default: "sqlsim") | +| `-l <seconds>` | Login timeout for replay connections | +| `-N`, `-C`, `-F` | Encryption settings for replay connections | +| `-R`, `-M` | High availability settings for replay connections | +| `-retry`, `-retrydelay` | Connection retry settings for replay connections | + +#### Incompatible Parameters + +The following parameters are **not supported** in replay mode and produce an error: + +| Parameter | Reason | +|-----------|--------| +| `-Q <query>` | Queries come from the replay file, not the command line | +| `-i <file>` | Queries come from the replay file, not an input file | +| `-p` | Replay uses its own ODBC methods per event type (SQLExecDirect, SQLPrepare+SQLExecute, etc.) | +| `-reconnect` | Replay manages its own connections per session | +| `-usepool` | Replay manages its own connections (depends on `-reconnect`) | + +> **Important:** When replaying to a different server or environment, be aware that: +> - Database names in the trace must exist on the target server +> - Stored procedures and tables referenced in the trace must exist +> - Permissions must be configured for the replay authentication method +> - Schema differences may cause errors that didn't occur in the original trace (these will show in the replay summary) + +> **Note on SET Options:** Replay does not capture or replay session-level SET options (`ANSI_NULLS`, `QUOTED_IDENTIFIER`, `ARITHABORT`, etc.) from the original application connections. ODBC Driver 18 applies standard defaults that match the behavior of most applications using modern drivers (ODBC, ADO.NET, JDBC). This is only a concern if the original workload was captured from an application using a non-standard driver with different SET defaults.

The stream emits `started`, periodic `progress`, and `completed` events. Progress is emitted once per second; short runs may contain only `started` and `completed`. Each line is flushed immediately. + +Streaming mode suppresses query results and human-readable output. Progress +and completed events include the ODBC driver version and SQL Server version +and edition after the first successful connection, along with aggregate +counters and rates. Events do not include SQL text, connection strings, +credentials, access tokens, or error messages. + +To retain the complete canonical result while monitoring the NDJSON stream, +combine `-stream-json` with `-json -o <file>`. The NDJSON events remain on +stdout and the final JSON document is written to the specified file after the +run completes. `-o` is required for the combined mode so the two JSON formats +never share one output channel: + +```powershell +sqlsim -S localhost -E -Q "SELECT 1" -stream-json -json -o final-results.json -q +``` + +```json +{"type":"started","timestamp":"2026-09-19T10:00:00.000","version":"1.0.0","threads":4} +{"type":"progress","timestamp":"2026-09-19T10:00:01.001","elapsed_seconds":1.001,"successful_connections":4,"failed_connections":0,"successful_executions":120,"failed_executions":0,"errors":0,"throughput_per_second":119.880,"odbc_driver_version":"18.05.0001","server_version":"16.0.4215.2","server_edition":"Developer Edition (64-bit)"} +{"type":"completed","timestamp":"2026-09-19T10:00:02.025","elapsed_seconds":2.025,"successful_connections":4,"failed_connections":0,"successful_executions":250,"failed_executions":0,"errors":0,"throughput_per_second":123.457,"odbc_driver_version":"18.05.0001","server_version":"16.0.4215.2","server_edition":"Developer Edition (64-bit)","status":"success"} +``` + +### JSON Output Structure + +The `-json` flag outputs structured JSON for programmatic parsing and integration with monitoring systems, automation pipelines, and data analysis tools. + +#### Compact Mode (`-json`) + +Basic JSON output includes core configuration and summary metrics.

Platform availability differs by ODBC Driver authentication mode; see [Linux Support](#linux-support) for the Linux matrix. + +### Method 1: Interactive Authentication (-A) + +Opens the ODBC Driver authentication UI for you to sign in with your Microsoft account. This mode is supported by the Windows ODBC driver only.

Measured against Azure SQL Database, one interactive connection took **about 12 seconds** to establish, versus roughly 1 second for the same target using `-T`. At `-n 100` that is 100 separate sign-in attempts: connection time dominates the measurement, Microsoft Entra may throttle the repeated requests, and you may be prompted more than once. +> +> Use `-A` for a connection check or a single-connection query.

Use `-T <token>` from a workstation instead. +> +> **Granting the identity an Azure RBAC role is not enough.** Microsoft Entra authentication for Azure SQL does not integrate with Azure RBAC. Roles such as *SQL DB Contributor* control management operations, not the ability to connect and query.

This ensures you're measuring server performance, not competing for resources with the database engine. +2. **Ensure Low Network Latency:** Position your client close to the server (same datacenter, VNET, or availability zone) to minimize network latency and isolate database performance. +3. **Use Quiet Mode:** `-q` suppresses result output, eliminating console I/O overhead for maximum throughput. +4. **Use Prepared Statements:** `-p` reduces parsing overhead for repeated queries. +5. **Size Your Client Appropriately:** High thread counts (1000+) require sufficient client CPU and memory. Monitor client resource usage to ensure it's not the bottleneck. +6. **Consider Multiple Client Instances:** For extreme load testing, run multiple sqlsim instances from different client machines to distribute the load generation. + +### For Load Testing + +1. **Start Small:** Begin with 1 thread, 1 iteration to verify queries work +2. **Scale Gradually:** Increase threads incrementally (10, 50, 100, etc.) +3. **Use Quiet Mode:** `-q` reduces output overhead for accurate metrics +4. **Set Timeouts:** Use `-l` and `-t` to prevent hung connections/queries +5. **Monitor Client and Server:** Watch CPU, memory, network, and connection usage on the load generator as well as SQL Server. Stop increasing concurrency when the client becomes the bottleneck. + +### For Development Testing + +1. **Use Verbose Mode:** `-v` shows detailed execution flow +2. **Test Authentication:** Verify each auth method works before load testing +3. **Validate Queries:** Run queries once before multi-threaded execution +4. **Use Scripts:** Create `.sql` files for repeatable tests + +### For Production Validation + +1. **Use Prepared Statements:** `-p` improves performance and security +2. **Set Conservative Timeouts:** Prevent resource exhaustion +3. **Log Results:** Redirect output to file for analysis: `> results.txt` + +[↑ Back to Table of Contents](#table-of-contents) + +## sqlsim vs sqlcmd - What's Different? + +While both sqlsim and [sqlcmd](https://learn.microsoft.com/en-us/sql/tools/sqlcmd/sqlcmd-utility) (the ODBC-based version) can execute SQL queries, **they serve fundamentally different purposes**. sqlcmd is a command-line SQL client for database administration and scripting. sqlsim is a specialized **performance testing and workload simulation tool** designed to help you understand how your database performs under real-world application loads. + +### Core Differences + +**sqlcmd** is designed for: +- Running administrative scripts and queries +- Interactive database exploration +- Batch file automation +- Sequential query execution + +**sqlsim** is designed for: +- **Load testing** - Simulate hundreds or thousands of concurrent users +- **Performance measurement** - Detailed metrics on connection, execution, and fetch times +- **Capacity planning** - Understand server limits and resource utilization +- **Application simulation** - Test real-world workload patterns +- **Connection behavior testing** - Test reconnects, pooling, retries, and timeouts + +### Unique Capabilities of sqlsim + +| **Capability** | **sqlsim** | **sqlcmd** | +|---------------|------------|------------| +| **Multi-threaded Execution** | ✅ 1-10,000 concurrent threads | ❌ Single-threaded only | +| **Connection-Only Testing** | ✅ Test connection overhead without queries | ❌ Not supported | +| **Performance Metrics** | ✅ Connection time, query elapsed time, fetch time, throughput (qps) | ❌ Basic query execution only | +| **Workload Simulation** | ✅ Simulate real application loads with multiple concurrent users | ❌ Sequential script execution | +| **Connection Behavior Testing** | ✅ Test reconnects (`-reconnect`), pooling (`-usepool`), retries (`-retry`/`-retrydelay`) | ❌ Not supported | +| **Prepared Statements** | ✅ Built-in prepared statement support (`-p`) | ❌ Not available | +| **Throughput Analysis** | ✅ Queries/second, rows/second metrics | ❌ No throughput analysis | +| **Statistical Analysis** | ✅ Avg times for connections and queries, per-query min/max/avg/total via `-querystats` | ❌ No performance statistics | +| **Load Testing** | ✅ Test query performance under concurrent load | ❌ Cannot simulate concurrent users | +| **Timeout Testing** | ✅ Test login and query timeout behavior with detailed messages | ⚠️ Basic timeout support | +| **Connection Stress Testing** | ✅ Test connection limits, pooling effectiveness, and resource limits | ❌ Not supported | +| **Application Name Tracking** | ✅ Set application name (`-app`) for session tracking | ⚠️ Limited support | +| **Stop on Error Control** | ✅ Choose to continue or stop on first error (`-stoponerror`) | ⚠️ Basic error handling | + +### When to Use sqlsim + +**✅ Use sqlsim when you need to:** + +1. **Performance Testing** + ```powershell + # Test query performance with 100 concurrent users + sqlsim.exe -S localhost -E -Q "SELECT * FROM Orders WHERE Status = 'Active'" -n 100 -r 10 + ``` + +2. **Connection Load Testing** + ```powershell + # Test connection limits with 500 concurrent connections (no queries) + sqlsim.exe -S myserver.database.windows.net -A -n 500 -r 5 + ``` + +3. **Connection Behavior Analysis** + ```powershell + # Test connection overhead with reconnects and retries + sqlsim.exe -S localhost -E -Q "SELECT 1" -r 100 -reconnect -retry 3 -retrydelay 5 -v + ``` + +4. **Application Workload Simulation** + ```powershell + # Simulate realistic application workload patterns + sqlsim.exe -S localhost -E -i workload.sql -n 50 -r 100 -p -q + ``` + +5. **Capacity Planning** + ```powershell + # Test server resource utilization and find breaking points + sqlsim.exe -S localhost -E -Q "SELECT COUNT(*) FROM LargeTable" -n 200 -r 50 + ``` + +6. **Authentication Performance Testing** + ```powershell + # Test Microsoft Entra authentication under load + sqlsim.exe -S mydb.database.windows.net -d mydb -A -n 25 -r 20 -Q "SELECT 1" + ``` + +7. **Timeout and Retry Behavior Testing** + ```powershell + # Test how application handles timeouts and retries + sqlsim.exe -S localhost -E -Q "WAITFOR DELAY '00:00:05';

On Linux or macOS, verify the + option is disabled and labelled **Windows only**. + - Managed identity: optional **User-assigned client ID**, no secret. + - Service principal: **Application (client) ID** and **Client secret**, both + required. Verify the option remains enabled for both engines. + - SQL authentication: username and password. + Switch from a mode with credentials to one without, and verify the previous + values are cleared rather than retained. +2. In a secret field, verify **Show** changes it to readable text and **Hide** + masks it again. Clear the field afterward. +3. Expand **Connection options**. Toggle **Trust server certificate** and verify + `-C` appears and disappears in Command preview. +4. Toggle **Stop on first error** and verify `-stoponerror` appears and + disappears. +5. Select telemetry modes and verify: + - Live progress: preview contains + `-stream-json -json -o studio-results.json`; `-q` is checked/disabled. + - Final results only: preview contains `-json -o studio-results.json`; `-q` + is checked/disabled. + - Console output: neither JSON flag is present; `-q` is available and off. +6. Select statistics modes and verify: + - Runtime messages adds `-querystats` for sqlsim. + - Query Store shows its preflight panel. + - None removes statistics flags. +7. Select sqlpysim and verify Replay is disabled, and that **Application + name** becomes empty and greyed out with the tooltip *Application name is + not supported with sqlpysim.* Mixed workload, Live progress, and Runtime + messages statistics must stay available. Switch back to sqlsim and confirm + any application name you had typed returns. +8. Verify required inputs have a red asterisk and the legend says **Required + fields**. Switch authentication modes and confirm only visible credential + fields become required. +9. Verify Test connection reports the live server version, edition, database, + and driver on success, and a specific error on failure. Verify remaining + unfinished controls are visibly disabled. +10. Enter a nonexistent database and select **Run workload**. Verify Studio + stays on Configure, reports the connection error beside **Test connection**, + and does not open Monitor or start a workload. +11. Verify workload estimates and connection summaries update in every mode: + Query and SQL File track connections x iterations (x batches for a file + with `GO` separators), Session order replay shows Replay passes and the + captured session count, Load stress shows Replay passes and selected stress + connections, and Mixed workload sums its groups. +11.

App Settings and Themes + +1. Hover **Studio ready** and verify the tooltip explains that the Studio app is + healthy while SQL target status appears when a workload runs. +2. Open the gear. Verify the dialog is titled **App settings** and says these + preferences do not change sqlsim workload settings. +3. Select Dark. Verify it previews immediately and that panels, inputs, monitor, + Results, Compare, log drawer, and console output remain legible. Confirm the + palette uses deep Cowboys navy, royal-blue actions, silver structure, and + white text rather than bright periwinkle accents. +4. Click Cancel. Verify the prior theme returns and is not saved. +5. Select Dark again and click OK. Refresh and verify Dark persists. +6. Preview Light and close with X. Verify Dark returns. +7. Select System, click OK, and verify Studio follows the operating-system + preference. +8. Select each color theme. Verify Blue, Red & Blue, Green & Black, and Green & + Gold color the whole screen, and Royal Blue and Green keep white panels with + a colored navigation rail. In every theme, verify text, inputs, buttons, and + the chart stay legible.

Query: Final Results and History + +Configure sqlsim, the authentication for this pass, your server, +`AdventureWorksLT`, one connection, one iteration, no statistics, and **Final +results only**. Run the contents of +[`examples/adventureworkslt/sql/medium-query.sql`](examples/adventureworkslt/sql/medium-query.sql) +twice without changing any setting. + +That file does one to three seconds of real server work per execution, which is +long enough to observe the running state. A sub-second query completes before +the state is visible. + +For each run verify: + +1. Monitor opens automatically. +2. The active state shows **Running...**, an animated pulse, target, elapsed + time, **View log**, and **Stop run**. +3. The waiting message says final structured results are pending. +4. Completion changes the action to **View results**. +5. Results shows success, nonzero runtime, one execution/connection, timing + bars, Query workload, target, driver, and engine version. +6. Open the execution log and verify it contains real sanitized events and no + credentials. + +| ID | Check | Expected | Result / evidence | +| --- | --- | --- | --- | +| QF-01 | First final run | Successful real Results | | +| QF-02 | Second identical run | Successful real Results | | +| QF-03 | Running state | Clear and continuously active | | +| QF-04 | Execution log | Real, sanitized entries | | + +## 5. Query: Console Rows + +This section tests that Studio displays result *rows*, so the queries return +several. A single-row query such as `SELECT COUNT(*)` cannot tell a complete +result from a truncated one: the first row is also the last. + +Select **Console output**, leave `-q` off, one connection and one iteration, +and run: + +```sql +SELECT TOP 10 CustomerID, FirstName, LastName +FROM SalesLT.Customer +ORDER BY CustomerID; +``` + +Verify **Capturing console output** while it runs, that Results opens +automatically, and that the console shows all ten rows: the column headers, +`1 | Orlando | Gee` first, `12 | Johnny | Caprio` last, and +`(10 row(s) affected)`. Fewer rows means output is being truncated. Different +names mean the sample database is not standard, rather than that console +capture failed. Structured metric panels should not claim JSON metrics that +this mode never produced. + +Repeat with sqlpysim: + +```sql +SELECT TOP 10 ProductID, Name +FROM SalesLT.Product +ORDER BY ProductID; +``` + +Expect ten rows, `680 | HL Road Frame - Black, 58` first and +`714 | Long-Sleeve Logo Jersey, M` last. + +sqlpysim prints a shorter summary after the rows than sqlsim does: no +**Performance Metric Summary** heading, and no start, end, average connect or +average elapsed lines. That is a known output-compatibility gap recorded in +[RELEASE-NOTES.md](../RELEASE-NOTES.md), not a defect in this run. The rows +themselves must match. + +| ID | Check | Expected | Result / evidence | +| --- | --- | --- | --- | +| QC-01 | sqlsim console rows | Ten rows, first and last as listed | | +| QC-02 | Automatic navigation | Results opens on completion | | +| QC-03 | sqlpysim console rows | Ten rows, first and last as listed | | + +## 6. Query: Live Progress and Cancellation + +For Live progress, set four connections, three iterations, and Studio server +statistics **Runtime messages**, then run the contents of +[`examples/adventureworkslt/sql/medium-query.sql`](examples/adventureworkslt/sql/medium-query.sql). + +That file does real server work for one to three seconds per execution, so a +single execution spans several one-second progress ticks. A sleeping query such +as `WAITFOR DELAY` holds the connection open without producing CPU, reads, or +query statistics, so it cannot show that live monitoring is measuring anything. + +Verify the Monitor shows structured start/progress/completed events, elapsed +time, throughput, executions, connections, errors, and progress, and that a +measured average duration appears beside the execution rate. Throughput stays +at zero until the first execution completes: the engine counts an execution +only on completion, so that is expected rather than a stall. After the first +query-statistics snapshot, verify **Live query statistics** shows totals, +average elapsed, server CPU, logical reads, execution share, and a per-query +row whose values update during the run. + +Then configure Final results only, raise the **Query timeout** above its 30 +second default, set eight connections and two iterations, and start the +contents of +[`examples/adventureworkslt/sql/heavy-query.sql`](examples/adventureworkslt/sql/heavy-query.sql). + +Click **Stop run** while active. The terminal state must be **Run stopped**, not +**Run failed**. + +| ID | Check | Expected | Result / evidence | +| --- | --- | --- | --- | +| QL-01 | Live telemetry | Events and metrics update | | +| QL-02 | Progress visualization | Bars visibly update | | +| QL-03 | Cancellation | Run stopped | | +| QL-04 | Measured duration | Real average shown, not zero | | +| QL-05 | Live query statistics | Totals, charts, and query table update | | + +## 7. Runtime Query Statistics + +Use sqlsim, Final results only, and **Runtime messages**. Run: + +```sql +SELECT 252 AS ManualRuntimeStatisticsResult; +``` + +Verify Results displays **Runtime query statistics** with real execution, +elapsed, CPU, and logical-read values. + +Then repeat the same run with sqlpysim selected. It gathers the same counters +from the execution plan rather than from `SET STATISTICS` output, so the panel +must appear with real values there too. + +| ID | Check | Expected | Result / evidence | +| --- | --- | --- | --- | +| STAT-01 | Runtime statistics | Real statistics panel shown | | +| STAT-02 | Runtime statistics on sqlpysim | Same panel, real values | | + +## 8. SQL File Mode + +Uses the tiered scripts in +[`examples/adventureworkslt/sql`](examples/adventureworkslt/sql). They run real +work against the sample schema, so this section proves Studio executes a +script rather than only that it can count `GO` separators. + +1. Select **SQL file** mode and choose + [`light-script.sql`](examples/adventureworkslt/sql/light-script.sql). +2. Before running, confirm Studio reports **4 batches** and that Total + executions tracks connections x iterations x batches. +3. Set one connection, one iteration, **Final results only**, and run. Verify + Results reports 4 batches with no errors. +4. Now choose + [`medium-script.sql`](examples/adventureworkslt/sql/medium-script.sql), + confirm Studio reports **3 batches**, set **4 connections** and **5 + iterations**, and run. Verify 60 batches complete with no errors. + +The medium script includes one deliberately expensive batch, so the run takes +a few seconds under concurrency rather than finishing instantly. That is what +makes the batch and execution counts worth checking. + +| ID | Check | Expected | Result / evidence | +| --- | --- | --- | --- | +| FILE-01 | Upload and batch count | 4 batches detected | | +| FILE-02 | Execution | 4 batches succeed | | +| FILE-03 | Concurrent script run | 3 batches x 4 x 5 = 60, no errors | | + +## 9. Mixed Workload Mode + +Covers both ways of building a workload: adding scripts by hand, and importing +a definition. They are different code paths, so both are tested. + +### Built by hand + +1. Add [`light-script.sql`](examples/adventureworkslt/sql/light-script.sql) and + [`medium-script.sql`](examples/adventureworkslt/sql/medium-script.sql) as two + groups. +2. Set the first to two connections / one iteration. +3. Set the second to one connection / two iterations / 1 ms think time. +4. Verify estimated executions and total connections update as you type. +5. Run with **Final results only** and verify two groups complete successfully. +6. Remove one group and verify the row disappears and totals recalculate. + +### Imported + +7. Choose **Import JSON** and select + [`light-workload.json`](examples/adventureworkslt/workload/light-workload.json). + Verify Studio reports **3 groups imported**, shows **7 total connections**, + and runs successfully. +8. Import `..\sqlsim\examples\workload\workload-test.json`, which is written + for the sqlsim command line rather than Studio. Verify Studio says it + **skipped 1 file-based group** and imports only the group with inline + queries. + +Step 8 matters because Studio cannot read a script that a definition refers to +by path: the browser has no access to it. A definition that imports with fewer +groups than it declares must say so rather than silently running a smaller +workload than the file describes. + +| ID | Check | Expected | Result / evidence | +| --- | --- | --- | --- | +| WORK-01 | Multiple groups | Two groups rendered | | +| WORK-02 | Per-group controls | Totals recalculate | | +| WORK-03 | Workload execution | Successful; two groups | | +| WORK-04 | Remove group | Row and totals update | | +| WORK-05 | Import JSON | 3 groups, 7 connections, runs clean | | +| WORK-06 | Skipped group reported | Says 1 file-based group was skipped | | + +## 10. Replay Modes + +Use the current test database. Confirm Replay initially selects Final results +only, then switch to Live progress for the Session order test. + +1. Select Replay and browse to + [`gui-tests/fixtures/replay-comparison.xml`](gui-tests/fixtures/replay-comparison.xml). + Verify preflight reports four captured and recognized events, zero skipped + events, two captured SPIDs, and no captured database context. Verify the + capture table lists SQL, event type, captured SPID, mode decision, and original + duration. +2. Confirm the privacy and behavior warning is visible. Select **Session order + (fast)**, verify Stress connections is disabled, enable **Collect per-query + performance**, select **Live progress**, set Replay passes to one, and run. + Confirm four events complete successfully and Monitor reaches 100%. +3. In Results, verify **Original capture vs Replay** shows original and Replay + outcomes, three exact SQL-text matches, original and Replay average elapsed + time, elapsed and read deltas, and zero failures. Verify Runtime query + statistics shows the same three queries with SPIDs, CPU, and I/O details. + Verify the SPIDs column shows which new SQL Server connection executed each query + and contains more than one distinct SPID across the Session order results. +4. Return to Configure, choose **Load stress**, verify Stress connections is + enabled, set it to two, and run one pass. Confirm eight events complete + successfully and Results labels the mode as transformed. +5. Select a malformed XML file and verify Studio rejects it before a run starts. + +The source-only comparison fixture contains read-only catalog queries and +records no database name, so it runs in the database selected in Studio and +does not issue `USE`. It is test data and is not embedded in the packaged +application. For an AdventureWorksLT-specific pass, use +[`examples/adventureworkslt/replay/portable-replay.xml`](examples/adventureworkslt/replay/portable-replay.xml); +preflight should report nine events across three captured SPIDs. That file contains +genuine captured duration, CPU, read, write, row-count, and outcome fields, so +its comparison must show original values and deltas rather than **Not +captured** or **Unavailable**. Select AdventureWorksLT as the target and verify +the preflight warning explains that Studio validates connectivity rather than +schema or data equivalence. + +| ID | Check | Expected | Result / evidence | +| --- | --- | --- | --- | +| REPLAY-01 | Replay fixture preflight | 4 recognized, 0 skipped, 2 captured SPIDs | | +| REPLAY-02 | Live Session order replay | Connections disabled; Monitor and 4 events complete | | +| REPLAY-03 | Live original vs Replay | 3 SQL matches; Runtime SPIDs; metrics; zero failures | | +| REPLAY-04 | Load stress replay | Connections enabled; 8 events ok; transformed label | | +| REPLAY-05 | Malformed XML | Rejected before execution | | +| REPLAY-06 | Single captured database | Captured context is redirected to the selected target | | +| REPLAY-07 | Multiple captured databases | Rejected during file preflight as unsupported in this release | | + +## 11. A/B Compare + +Runs last, once every workload type has been exercised. Compare reads the run +history, so it can only be judged against a history that has something in it. +AB-04 in particular asks you to confirm that console and live runs are absent, +which means nothing until those runs have actually been performed. + +1. Open **Compare**. +2. Select the two identical Final-results runs from section 4. Confirm both + appear and **Runs are comparable** is shown. +3. Verify throughput, total duration, average execution, average connection, + errors, normalized bars, verdict counts, target, workload hash, load shape, + and statistics source are populated from the selected runs. +4. Click **Swap** and verify baseline and candidate values, and their deltas, + reverse. +5. Select one of those runs against the SQL file or workload run from sections + 8 and 9. Studio must say the runs are not comparable and must hide the + deltas: a different workload shape is not a like-for-like comparison. +6. Review the history list. The console run from section 5 must **not** + appear, because it does not produce final JSON. Completed Final-results and + Live-progress runs should appear. Select one Live-progress run against a + Final-results run with the same workload and confirm Studio refuses the pair + because telemetry differs. +7. On Results, use **Export JSON** for the two identical Final-results runs. + In Compare, use **Import JSON** above Baseline and Candidate to load those + files. Confirm the imported labels appear and **Runs are comparable** is + shown. Import the SQL file or workload result as Candidate and confirm the + comparison is rejected. +8. Import `sqlsim/examples/results/index-baseline.json` as Baseline and + `index-candidate.json` as Candidate. Confirm **Per-query comparison** shows + the customer lookup with logical reads changing from 36.0 to 2.0. + +| ID | Check | Expected | Result / evidence | +| --- | --- | --- | --- | +| AB-01 | Compatible pair | Real metrics and verdict | | +| AB-02 | Swap | A/B values reverse | | +| AB-03 | Incompatible pair | Rejected; no deltas | | +| AB-04 | History eligibility | Completed Final and Live runs appear; console runs absent | | +| AB-05 | Imported results | Compatible files compare; incompatible import rejected | | +| AB-06 | Per-query comparison | Matched query shows A/B values and changes | | + +## 12. Optional Query Store + +Only run after Query Store preflight passes. Use Final results only and Query +Store statistics: + +```sql +SELECT TOP (10) name +FROM sys.objects +ORDER BY object_id; +``` + +Verify Results displays **Query Store statistics**, exact submitted SQL text, +and aggregate deltas.

Responsive and Browser Pass + +Repeat the navigation and one Final-results query in each required browser for +the current platform. On Windows, test current Edge and Chrome. + +Before this pass, run the automated responsive sweep +(`gui-tests/responsive.config.cjs`, described in README.md). It covers desktop +widths from 761 to 2560 pixels in Edge, Chrome, Firefox, WebKit, and a wide-font +pass; this manual pass confirms real-browser behavior it cannot observe. + +At approximately 390 x 844 and 1440 x 1000 verify: + +- No horizontal page overflow. +- Text and controls do not overlap or clip. +- Tabs, Configure panels, Monitor, Results, Compare, log drawer, and console + output remain usable. +- Browser developer console contains no errors or CSP violations. +- Required asterisks are clearly visible in red. +- Field labels and supporting text remain readable at projection distance. +- The darker silver canvas distinguishes white panels without reducing text + contrast. + +| ID | Browser / viewport | Expected | Result / evidence | +| --- | --- | --- | --- | +| UI-01 | Edge desktop | No layout/console errors | | +| UI-02 | Edge mobile viewport | No overflow/overlap | | +| UI-03 | Chrome desktop | No layout/console errors | | +| UI-04 | Chrome mobile viewport | No overflow/overlap | | + +## 14.

Do not treat the +current application as release-ready. + +## Connecting to Azure SQL with Microsoft Entra + +Select **Microsoft Entra token** and paste an access token for the SQL Server +audience into the credential field. Acquire one with the Azure CLI: + +```powershell +az login +az account get-access-token --resource https://database.windows.net --query accessToken -o tsv +``` + +Studio passes the token to the engine over standard input, never on the command +line, and never writes it to a saved configuration or a log. Tokens are +short-lived, so repeat the command when a run fails to authenticate. + +Use **Test connection** after pasting the token to confirm the target, database, +and encryption settings before starting a workload. + +Microsoft Entra interactive, managed identity, and service principal are +available through Studio. Interactive authentication is Windows-only; managed +identity and service principal require a suitably configured Azure target. + +**Save configuration** downloads the selected mode and its settings as a +versioned `.json` file on the user's computer. SQL scripts and replay content are +included so the configuration can be restored without selecting those files +again. Passwords and tokens are never included, and loading any configuration +clears the current secret field. Treat saved configurations as sensitive when +their query or script text contains environment-specific information. + +See [CONFIGURATION.md](CONFIGURATION.md) for the version 1 JSON contract, +mode-specific source objects, validation limits, security rules, and examples. + +## Build on Windows + +```powershell +cd sqlsimstudio +.\build.ps1 +``` + +The self-contained Windows x64 output is written to `build/win-x64/`. +The package contains the Studio executable, the matching native sqlsim binary, +sqlpysim source, requirements, the released-product Studio skill, notices, and +no separate browser asset folder. +sqlpysim remains optional. To enable it, create `.venv` beside the Studio +executable, or in the folder above it as the sqlsimtools package does, and +install `sqlpysim/requirements.txt`. Studio uses `SQLSIM_STUDIO_PYTHON_PATH` +first, then those two `.venv` locations, then `python` on `PATH`; see +[Install sqlsim Studio](../INSTALL.md#install-sqlsim-studio). + +Windows ARM64 is a Private Preview build. Building it from source requires a +matching native ARM64 sqlsim build at `..\sqlsim\build\ARM64\Release\sqlsim.exe`: + +```powershell +cd sqlsimstudio +.\build.ps1 -Runtime win-arm64 +``` + +The output is written to `build/win-arm64/`. It must be validated on native +Windows ARM64 hardware before promotion beyond Private Preview. + +## Build Linux Locally with WSL2 + +Cross-publish the self-contained Linux binary from Windows, then execute and +validate that native binary inside WSL2. The WSL distribution does not need a +.NET runtime or SDK. + +```powershell +.\build.ps1 -Runtime linux-x64 +wsl -d Ubuntu -- bash -lc 'cd /mnt/c/sqlsimtools/sqlsimstudio && bash ./smoke-test-linux.sh' +``` + +The self-contained Linux x64 output is written to `build/linux-x64/`. + +## Run During Development + +```powershell +dotnet run --project .\server\SqlsimStudio.csproj +``` + +Studio binds only to loopback and opens the default browser. For automated testing, `--no-open` requires `--bootstrap-file <path>` so the one-time token is not written to logs. Studio deletes the file after successful bootstrap. + +```powershell +.\smoke-test.ps1 +``` + +## Error Handling and Validation Suite + +`smoke-test.ps1` proves the happy path works. `full-test-suite.ps1` proves Studio +fails correctly: that bad input is rejected with a specific reason, that the +security boundary holds, and that a failed workload reports why. + +```powershell +# Everything, including the live failure-reporting sections +.\full-test-suite.ps1 + +# Only the sections that need no SQL Server +.\full-test-suite.ps1 -OfflineOnly + +# Against a packaged build +.\full-test-suite.ps1 -SkipBuild -StudioExecutable .\build\win-x64\sqlsimstudio.exe +``` + +| Section | Covers | Needs SQL | +| --- | --- | --- | +| 1. Startup and argument handling | Exit codes, usage output, no leaked stack traces | No | +| 2. Authentication boundary | 404 for unauthenticated, bootstrap replay, Host and Origin | No | +| 3. Request validation - connection | Connection-string injection, credential rules per mode, limits | No | +| 4. Request validation - workload shape | Mode, load shape, file extensions, group limits | No | +| 5. Request validation - engine capability | Every sqlpysim restriction | No | +| 6. Request validation - execution options | Telemetry, statistics, pooling, timeouts | No | +| 7. Payload limits | 1 MB query and file, 10 MB workload, malformed JSON | No | +| 8. App settings | Saved theme file, allow-list validation, origin and session checks, restart persistence, corrupt-file tolerance | No | +| 9. Connection failure reporting | Unreachable port, missing database, complete success fields | Yes | +| 10. Workload failure reporting | SQL error reaches the log, exit code, credential never logged, stop vs fail | Yes | +| 11. Concurrency and lifecycle | Second run refused, test refused during a run, stop with nothing running | Yes | + +Every rejection test asserts the specific error text rather than just a 400, so a +change that returns the wrong reason fails the suite. + +## Automated GUI Smoke Test + +The Playwright suite has two tiers. + +`gui-tests/interface.spec.cjs` and `gui-tests/configuration.spec.cjs` load +`client/index.html` directly over `file://`. They need no Studio process, no SQL +target, and finish in seconds, so they are safe to run anywhere: + +```powershell +.\node_modules\.bin\playwright.cmd test --config gui-tests/playwright.config.cjs ` + gui-tests/interface.spec.cjs gui-tests/configuration.spec.cjs +``` + +`gui-tests/responsive.spec.cjs` is a layout sweep over the same `file://` client. +It fills Configure, Monitor, Results, Compare, and the settings dialog with +realistic data, then checks 19 desktop widths from 761 to 2560 pixels for +horizontal page overflow and for text that escapes its box, is clipped, overlaps +other text, or wraps in a label, heading, or button. It runs in Edge (150% +scaling), Chrome (125% scaling), Firefox, WebKit (Safari's engine), and a +wide-font pass that substitutes Verdana for the Windows-only interface fonts, +approximating macOS and Linux fallback fonts: + +```powershell +.\node_modules\.bin\playwright.cmd install firefox webkit +.\node_modules\.bin\playwright.cmd test --config gui-tests/responsive.config.cjs +# One engine only +.\node_modules\.bin\playwright.cmd test --config gui-tests/responsive.config.cjs --project firefox +``` + +Set `SQLSIMSTUDIO_RESPONSIVE_SCREENSHOTS=1` to save full-page screenshots under +`build/responsive-screenshots/<project>/` at common widths and wherever a +defect is found. + +`gui-tests/studio.spec.cjs` starts the packaged Studio server with a private +one-time bootstrap file and drives a real browser through connection controls, +workload modes, output modes, cancellation, Results, session history, and A/B +comparison against a live SQL target. It captures screenshots, video, and traces +under `build/` when a test fails. + +```powershell +.\gui-smoke-test.ps1 +``` + +Use `-SkipBuild` to reuse the current `win-x64` package, `-Headed` to watch the +browser, `-CaptureScreenshots` to save desktop/mobile Configure views under +`build/gui-screenshots/`, or `-Server` and `-Database` for another +integrated-authentication target. Query Store coverage is optional and +preflighted before browser launch: + +```powershell +.\gui-smoke-test.ps1 -SkipBuild -QueryStoreDatabase AdventureWorks +``` + +The suite defaults to Microsoft Edge. Pass `-BrowserChannel chromium` to use +Playwright's own bundled browser instead, which requires no installed Edge or +Chrome: + +```powershell +.\node_modules\.bin\playwright.cmd install chromium +.\gui-smoke-test.ps1 -SkipBuild -BrowserChannel chromium +``` + +Authentication modes requiring credentials are checked for correct UI state but +are not executed unless a future secure credential fixture is added. The suite +never writes credentials to command lines, logs, screenshots, or traces. + +Use [MANUAL-TEST.md](MANUAL-TEST.md) for the corresponding recordable manual +acceptance pass, expected outcomes, evidence fields, and known-gap inventory. +In VS Code chat, invoke `/sqlsimstudio-manual-test start` for a guided, +one-test-at-a-time session that records outcomes and can resume later. + +## Browser Security Boundary + +The local browser is not trusted merely because it runs on the same machine. Studio requires a one-time bootstrap token and authenticated session cookie, rejects unexpected Host and Origin headers, disables CORS, and returns 404 to unauthenticated requests. Future workload mutation APIs must also require anti-forgery validation. + +Secrets must never be persisted or placed in child-process arguments. Studio will invoke sqlsim or sqlpysim with `-P -` or `-T -` and write the credential through redirected stdin. + +Query Store collection uses Microsoft.Data.SqlClient only for read-only snapshots +before and after a workload. It requires Query Store in `READ_WRITE` state and +`VIEW DATABASE STATE`, or `VIEW DATABASE PERFORMANCE STATE` on SQL Server 2022 +and later. Deltas are aggregated and can include other sessions executing the +same query during the measurement window. + +## Third-Party Software + +See [THIRD-PARTY-NOTICES.md](THIRD-PARTY-NOTICES.md). diff --git a/sqlsimstudio/THIRD-PARTY-NOTICES.md b/sqlsimstudio/THIRD-PARTY-NOTICES.md new file mode 100644 index 0000000..231640b --- /dev/null +++ b/sqlsimstudio/THIRD-PARTY-NOTICES.md @@ -0,0 +1,31 @@ +# Third-Party Notices + +## Lucide 0.468.0 + +- Project: https://lucide.dev/ +- Source: https://github.com/lucide-icons/lucide +- Vendored file: `client/vendor/lucide.min.js` +- SHA-256: `3411692820CB8D47543F69496AA25FD603A358F4498046F41C508A5A3342210E` +- License: ISC + +Copyright (c) for portions of Lucide are held by Cole Bemis 2013-2022 as part of Feather (MIT).

+ + + +
+

End this session

Shut down sqlsim Studio

+ +
+
+

Any running workload will be terminated. Studio stops the sqlsim or sqlpysim process it started, closes every connection that process holds open on your database, deletes this session's temporary files, and exits. This page will stop working.

Studio cannot read scripts referenced by a +`file` property and silently skips any group that has one, so a definition +written for the sqlsim CLI may import with fewer groups than it declares. None +of these files set `duration_seconds`, which sqlsim honors but Studio ignores. + +## Replay mode + +| Tier | File | Sessions | Events | +| --- | --- | --- | --- | +| Any | [`replay/portable-replay.xml`](replay/portable-replay.xml) | 3 | 9 | + +Fast mode is faithful per session and replays all 9 events. Stress mode flattens +them into one pool, so N connections replay N x 9. + +The fixture contains genuine `sql_batch_completed` events captured from three +concurrent sqlsim sessions against AdventureWorksLT. Each event includes its +original duration, CPU, logical and physical reads, writes, row count, outcome, +and session ID. Enable **Collect per-query performance** in Studio to populate +the full **Original capture vs Replay** comparison. + +The capture intentionally records no database action, so replay issues no +`USE` and runs in the database the connection specifies. Its batches are +`SalesLT` qualified, so they only resolve if the connection context is correct. +Original timings describe one local capture only; use them to validate the +comparison workflow, not as a portable performance baseline. +Select AdventureWorksLT as the Studio target before running. Studio validates +that connection but cannot validate schema or data equivalence; the selected +database must contain the AdventureWorksLT schema and synchronized test data +for the comparison to be meaningful. For a Replay pass that needs no sample +database, use `../any-database/replay/catalog-replay.xml`. + +The replay fixtures in the source repository's `sqlsim/testing` folder are +different on purpose. +`clean-replay.xml` alternates between `master` and `tempdb` because exercising +database switching is the point of it, and `replay-test-data.xml` records +`master` on every event. Both make sqlsim issue `USE`, which Azure SQL Database +does not support for switching databases. Use them for sqlsim's own replay +coverage, not for a portable Studio pass. + +## Before running the heavy tier + +1. **Raise the query timeout.** The default is 30 seconds and a heavy execution + can exceed it under concurrency. A timeout is a valid test, but it is not + this one. +2. **On Azure SQL Database, halve the connections.** On a small service tier the + heavy tier measures throttling rather than client behavior. +3. **Expect a long run.** The heavy workload is 16,650 batches. + +## Reading the measurements + +Durations in these files were measured on an Intel i7-1370P against a warm +cache. Treat them as relative rather than absolute. That part is a hybrid +design, and identical runs land in two clusters more than 2x apart depending on +whether the worker is scheduled on a performance or an efficiency core. Take the +median of several runs before reading anything into a timing change, and +re-measure on each new host rather than carrying these numbers forward. A cold +cache roughly doubles the first execution. + +## Adjusting cost + +The medium and heavy SQL files carry a tally CTE whose `TOP` value is the cost +dial. Rows evaluated is that value multiplied by 295, the row count of +`SalesLT.Product`, and duration tracks it closely: + +| `TOP` | Rows evaluated | Duration | +| --- | --- | --- | +| 3,000 | 885,000 | under 1 s | +| 10,000 | 2,950,000 | 1 s to 3.5 s | +| 80,000 | 23,600,000 | 9 s to 25 s | + +Prefer this dial over cross-joining the sample tables against each other. The +sample is small, and growing a table cross join changes the plan rather than the +cost: tripling the row count that way was measured to raise the duration only 20 +percent, which makes it useless as a dial. diff --git a/sqlsimstudio/examples/adventureworkslt/replay/portable-replay.xml b/sqlsimstudio/examples/adventureworkslt/replay/portable-replay.xml new file mode 100644 index 0000000..dddb147 --- /dev/null +++ b/sqlsimstudio/examples/adventureworkslt/replay/portable-replay.xml @@ -0,0 +1,328 @@ + + + + + + 0 + + + 100 + + + 0 + + + 0 + + + 5 + + + 0 + + + 0 + + + 1 + + + 0 + + + + + + + 61 + + + + + 0 + + + 52 + + + 0 + + + 0 + + + 5 + + + 0 + + + 0 + + + 10 + + + 0 + + + + + + + 61 + + + + + 0 + + + 63 + + + 0 + + + 0 + + + 4 + + + 0 + + + 0 + + + 1 + + + 0 + + + + + + + 61 + + + + + 0 + + + 1128 + + + 0 + + + 0 + + + 3 + + + 0 + + + 0 + + + 5 + + + 0 + + + + + + + 67 + + + + + 0 + + + 445 + + + 0 + + + 0 + + + 105 + + + 0 + + + 0 + + + 41 + + + 0 + + + + + + + 67 + + + + + 0 + + + 93 + + + 0 + + + 0 + + + 4 + + + 0 + + + 0 + + + 1 + + + 0 + + + + + + + 67 + + + + + 0 + + + 84 + + + 0 + + + 0 + + + 2 + + + 0 + + + 0 + + + 10 + + + 0 + + + + + + + 68 + + + + + 0 + + + 129 + + + 0 + + + 0 + + + 2 + + + 0 + + + 0 + + + 1 + + + 0 + + + + + + + 68 + + + + + 0 + + + 108 + + + 0 + + + 0 + + + 2 + + + 0 + + + 0 + + + 5 + + + 0 + + + + + + + 68 + + + \ No newline at end of file diff --git a/sqlsimstudio/examples/adventureworkslt/sql/heavy-query.sql b/sqlsimstudio/examples/adventureworkslt/sql/heavy-query.sql new file mode 100644 index 0000000..a08f2a7 --- /dev/null +++ b/sqlsimstudio/examples/adventureworkslt/sql/heavy-query.sql @@ -0,0 +1,32 @@ +-- HEAVY tier -- sqlsim Studio Query mode +-- Requires AdventureWorksLT.

It is a self-contained desktop application, +not a remote service: the packaged executable starts a web server bound only to +loopback, opens your default browser, and runs workloads as child processes +using the packaged `sqlsim` binary or an optional `sqlpysim` Python install. + +**Important:** sqlsim Studio drives the same workload engines as the `sqlsim` +command line and is subject to the same guidance. It is a **testing and +workload simulation tool** for development, test, and performance evaluation +environments. It is **not intended for use against production systems**. High +connection counts can generate significant load that affects availability and +reliability. Always target dedicated test environments. + +**Preview status:** Windows x64 is Public Preview. Ubuntu x64, Windows ARM64, +and macOS ARM64 are Private Preview for invited testers while platform +validation and packaging are completed. + +**Key capabilities:** + +- Four workload modes: single query, SQL script file, mixed workload, and XEvent replay +- Two execution engines: native `sqlsim` (ODBC) and `sqlpysim` (`mssql-python`) +- Live throughput and per-query statistics, or maximum-performance runs with final results only +- Console mode for viewing actual result rows +- Bounded in-session run history with guarded A/B comparison of session runs and saved result files +- Optional per-query statistics from runtime messages or Query Store deltas +- Connection testing against the exact settings a run will use +- Versioned JSON configuration save and load, with secrets excluded +- Light, dark, system, and six color themes + +**How this tool was built:** +100% of the code, scripts, and documentation for sqlsim Studio was developed with +GitHub Copilot in Visual Studio Code using various AI models, but 100% orchestrated by Bob +Ward. + +## Installation + +1.

Extract it to a folder you control, for example `C:\Tools\sqlsimtools`. +3. Run `sqlsimstudio\sqlsimstudio.exe`. + +There is no installer and no separate runtime to install.

Refresh Studio after +installing. Studio chooses Python from `SQLSIM_STUDIO_PYTHON_PATH`, then `.venv` +beside `sqlsimstudio.exe`, then `.venv` in the sqlsimtools folder, then `python` +on `PATH`. Double-clicking Studio does not activate a virtual environment you +created somewhere else; use one of those `.venv` locations or set +`SQLSIM_STUDIO_PYTHON_PATH`. + +The **Execution engine** list reports **Python not found** or **mssql-python +not installed** when sqlpysim cannot run. + +### Disk and memory use + +The sqlsimtools Windows x64 package is about 61 MB to download and 142 MB +extracted. Nearly all of that is Studio: the bundled .NET runtime inside +`sqlsimstudio.exe` (about 104 MB) and the ICU globalization libraries (about +35 MB). If you only need the command-line tools, the `sqlsim` and `sqlpysim` +packages are each under 1 MB to download and do not include Studio. + +Studio runs each workload in a separate engine process, so memory is split +between Studio and the engine. Measured peaks on Windows x64 against a local +SQL Server: + +| Scenario | Studio | Engine process | Total | +| --- | --- | --- | --- | +| Idle, signed in | 58 MB | — | 58 MB | +| sqlsim, 8 connections, Live progress and runtime statistics | 74 MB | 19 MB | ~95 MB | +| sqlsim, 100 connections, Live progress and runtime statistics | 73 MB | 42 MB | ~115 MB | +| sqlsim, 100 connections, Final results | 72 MB | 42 MB | ~115 MB | +| sqlpysim, 8 connections, Live progress and runtime statistics | 72 MB | 51 MB (Python) | ~125 MB | + +Values are working-set memory. Connection count mainly grows the engine +process, by roughly 0.25 MB per connection for sqlsim; Studio itself stays +nearly flat and returns to about 72 MB after runs finish. Studio keeps the +current session's runs for [Compare](#comparing-runs), up to 50 runs. The +browser tab that displays Studio uses additional memory that is not included +here. Results vary with the workload, result-set sizes, and query statistics +collected. + +## Getting Started + +Run `sqlsimstudio\sqlsimstudio.exe`. Studio starts on a random loopback port and opens your +default browser to a one-time bootstrap address. No console window appears: +Studio's interface is the browser. When it is launched from a terminal it still +reports its address there: + +```text +SQLSIM_STUDIO_URL=http://127.0.0.1:62967 +``` + +The bootstrap URL contains a single-use 256-bit token that establishes an +authenticated session cookie. Once consumed it cannot be reused, but Studio +immediately writes a replacement into the session file, so there is always +exactly one unused token available while it runs. + +**To stop Studio, use the power button in the top right.** It confirms first, +warning you if a workload is still running, then stops the workload, deletes +the private run directory, and exits. This is the only deliberate exit: Studio +has no window of its own and no usable Ctrl+C, because the binary is a GUI +subsystem process. Launched by double click there is no console at all; +launched from a terminal the prompt returns immediately, so Studio never holds +the foreground. + +**Closing the browser does not stop Studio.** A workload outlives the page that +started it, which is what you want from a load test: a mis-click on a tab +should not abandon a run halfway through. If a workload is running when you +close the tab, the browser asks you to confirm first — its wording is generic +and cannot be changed, so the Monitor also carries a note explaining what is +about to happen. To get the interface back, open the URL in the session file: + +```text +%TEMP%\sqlsimstudio-session-.url +``` + +On macOS the file is in your private temporary directory (`$TMPDIR`). On +Linux, where `/tmp` is shared with other users, it is +`~/.local/share/sqlsimstudio/session.url` in a directory only you can read, +and private run files are under `~/.local/share/sqlsimstudio/runs`. + +Studio does not watch the browser at all. Earlier versions inferred a closed +browser from a page that had gone quiet, and every version of that guess was +wrong in the same way: a backgrounded tab, a tab frozen by the browser, and a +sleeping laptop all look identical to a closed one, so Studio would stop a +session that was still in use. + +If Studio is killed rather than shut down, the engine process survives and +keeps running the workload against your database. Collect it from the +sqlsimtools folder with: + +```powershell +.\sqlsimstudio\sqlsimstudio-cleanup.ps1 -WhatIf # report only +.\sqlsimstudio\sqlsimstudio-cleanup.ps1 # stop orphans, remove stale run directories +``` + +**Your first run:** + +1. Enter a **Database**. It is required; there is no default. +2. Leave **Server** as `localhost`, or enter your target. +3. Leave **Authentication** as Windows / Kerberos integrated for a local server. +4. Click **Test connection** and confirm the server details come back. +5. Select the **Query** workload mode. +6. Accept the default query and load shape, or edit them. +7. Click **Run workload**. + +Studio switches to the Monitor view automatically, then to Results when the run +completes. + +## Command-Line Options + +```text +Usage: sqlsimstudio [--no-open --bootstrap-file ] [--port ] +``` + +| Option | Description | +| --- | --- | +| `--port ` | Bind to a specific loopback port instead of a random one. | +| `--no-open` | Do not launch a browser. Requires `--bootstrap-file`. | +| `--bootstrap-file ` | Write the one-time bootstrap URL to a file instead of a log. Studio deletes the file after successful bootstrap. | +| `-h`, `--help` | Show usage and exit. | + +`--no-open` exists for automated testing. The bootstrap URL is written to a file +rather than standard output so the single-use token is not captured in logs or +terminal scrollback. + +## The Studio Interface + +Studio has four views, selected from the tabs in the title bar: + +| View | Purpose | +| --- | --- | +| **Configure** | Build the run: connection, workload, and execution settings | +| **Monitor** | Watch an active run: throughput, progress, events, and log | +| **Results** | Inspect the completed run's metrics and configuration | +| **Compare** | A/B two completed runs from this session or saved JSON result files | + +The Configure view is organized as three numbered panels — Connection, Workload, +and Execution — with a persistent command preview and **Run workload** button at +the bottom. Required fields are marked with a red asterisk. + +The status badge in the header shows the running Studio version, for example +**Studio ready · v1.0.0**. The Execution engine list shows the version reported +by each packaged engine, such as **sqlsim 1.0.0 · Native ODBC**. If an engine is +missing, the list says **not found**. + +## Step 1 - Connection + +| Field | Default | Notes | +| --- | --- | --- | +| Execution engine | `sqlsim` | See [Choosing Between sqlsim and sqlpysim](#choosing-between-sqlsim-and-sqlpysim) | +| Server | `localhost` | Host, `host,port`, or `host\instance` | +| Database | *(empty, required)* | Studio always sends `-d` | +| Authentication | Windows / Kerberos integrated | See [Authentication](#authentication) | + +### Connection options + +Expand **Connection options** for settings that map directly to `sqlsim` flags: + +| Control | Flag | Default | Notes | +| --- | --- | --- | --- | +| Login timeout | `-l` | 15 sec | 0 to 86,400. 0 waits indefinitely. | +| Application name | `-app` | `sqlsimstudio` | Appears as `program_name` in `sys.dm_exec_sessions` | +| Encryption | `-N` | Mandatory | Mandatory, Strict (TDS 8.0), Optional, or Driver default | +| Retry count | `-retry` | 0 | 0 to 255 connection retries | +| Trust server certificate | `-C` | Checked | Skips certificate validation | +| Read-only application intent | `-R` | Off | Routes to a readable secondary | + +Advanced execution options add: + +| Control | Flag | Notes | +| --- | --- | --- | +| Multi-subnet failover | `-M` | For Always On availability groups | +| Certificate hostname | `-F` | Expected name when it differs from the server name | + +**About the encryption defaults.** Studio defaults to Mandatory encryption with +Trust server certificate checked, matching SQL Server Management Studio. This is +appropriate for test servers using self-signed certificates. For a server with a +certificate issued by a trusted authority, clear **Trust server certificate** so +the certificate is actually validated. Choose **Strict** for TDS 8.0. + +Note that the `sqlsim` command line behaves differently when invoked directly: +if neither `-N` nor `-C` is supplied it silently uses +`TrustServerCertificate=Yes`. Studio always sends an explicit encryption choice, +so what you see in the command preview is what you get. + +## Authentication + +Six modes are available: + +| Mode | Flags | Credentials | +| --- | --- | --- | +| Windows / Kerberos integrated | `-E` | None | +| Microsoft Entra token | `-T` | Access token | +| Microsoft Entra interactive | `-A ActiveDirectoryInteractive` | None. Windows only | +| Managed identity | `-A ActiveDirectoryMsi` | Optional user-assigned client ID | +| Service principal | `-A ActiveDirectoryServicePrincipal` | Client ID and secret | +| SQL authentication | `-U` / `-P` | Username and password | + +Studio shows only the fields a mode actually uses, and clears them when you +switch to a mode that does not. It enforces the same credential rules the +engines do, so an unusable combination is refused before a process starts rather +than failing partway into a run. + +### Windows / Kerberos integrated + +Emits `-E`. No credential fields. The default for local SQL Server. + +### Microsoft Entra token + +Emits `-T` and passes the token to the engine over standard input. Requires an +access token for the SQL Server audience. Acquire one with the Azure CLI: + +```powershell +az login +az account get-access-token --resource https://database.windows.net --query accessToken -o tsv +``` + +Paste the value into **Password / token**. This is the supported path for Azure +SQL Database, Azure SQL Managed Instance, and SQL database in Microsoft Fabric. +It is also the recommended path for repeated runs because it avoids an +interactive sign-in prompt each time. + +Tokens are short-lived, typically about an hour. If a run that previously +worked starts failing authentication, acquire a new token. + +### SQL authentication + +Emits `-U` with the username and `-P` with the password over standard input. + +### Microsoft Entra interactive + +Emits `-A ActiveDirectoryInteractive` and opens a browser sign-in prompt. Takes +no credential fields. + +**Windows only.** ODBC Driver 18 implements interactive sign-in on Windows and +nowhere else, so Studio disables this option when running on Linux or macOS and +labels it accordingly. Use an access token or a managed identity there. + +> **Do not use interactive sign-in for a multi-connection workload.** Every +> connection performs its own sign-in round trip. Measured against Azure SQL, a +> single interactive connection took **about 12 seconds** to establish, against +> roughly 1 second for the same target using an access token. At `-n 100` that +> is 100 separate sign-in attempts, and the connection time dominates whatever +> you were trying to measure. Entra may also throttle or block the repeated +> requests, and you may be prompted more than once. +> +> Use interactive sign-in for **Test connection** or a single-connection check. +> For any real workload, use **Microsoft Entra token**: acquire it once, and +> every connection reuses it. + +### Managed identity + +Emits `-A ActiveDirectoryMsi`. No secret is ever accepted; Studio rejects the +request if one is present, matching the engine. + +Leave **User-assigned client ID** empty to use the system-assigned identity, or +enter an identifier to select a user-assigned one. Azure VMs expect the +identity's **object ID**; App Service expects its **client ID**. + +**Two requirements, and both are easy to miss.** + +**1. Studio must be running on an Azure resource that has a managed identity.** +The driver retrieves the token from the Azure Instance Metadata Service at +`169.254.169.254`, a link-local address that only exists inside Azure compute. +A developer workstation has nothing listening there, so this mode cannot work +locally no matter what permissions you hold. Run Studio on an Azure VM, VM Scale +Set, App Service, Container App, Azure Functions host, or AKS node with an +identity assigned. On a workstation, use **Microsoft Entra token** instead. + +**2. The identity must exist as a principal inside the target database.** +Microsoft Entra authentication for Azure SQL does not integrate with Azure RBAC. +Assigning the identity a role such as *SQL DB Contributor* grants management +permissions, not the ability to connect and query. Connect as a Microsoft Entra +admin and create the principal explicitly: + +```sql +-- System-assigned identity: the name is the Azure resource name. +CREATE USER [my-vm-name] FROM EXTERNAL PROVIDER; +ALTER ROLE db_datareader ADD MEMBER [my-vm-name]; + +-- User-assigned identity: the name is the identity's name. +CREATE USER [my-managed-identity] FROM EXTERNAL PROVIDER; +ALTER ROLE db_datareader ADD MEMBER [my-managed-identity]; +``` + +A new database user receives `CONNECT` by default. Grant anything beyond that +explicitly, and prefer adding the identity to a role over granting directly. + +Azure SQL requires principal names to be unique, while Microsoft Entra allows +duplicate display names. If creation fails for that reason, disambiguate with +the object ID: + +```sql +CREATE USER [my-identity] FROM EXTERNAL PROVIDER + WITH OBJECT_ID = 'aaaaaaaa-0000-1111-2222-bbbbbbbbbbbb'; +``` + +Verify the principal exists before running a workload: + +```sql +SELECT name, type_desc FROM sys.database_principals WHERE type_desc = 'EXTERNAL_USER'; +``` + +See [Configure and manage Microsoft Entra authentication with Azure SQL](https://learn.microsoft.com/azure/azure-sql/database/authentication-aad-configure) +for the full procedure. + +### Service principal + +Emits `-A ActiveDirectoryServicePrincipal` with `-U` for the application +(client) ID and `-P` for the client secret over standard input. Both are +required. + +Not supported by `sqlpysim`, whose `-A` handles interactive and managed identity +only. Studio disables the option when the Python engine is selected. + +### Credential handling + +Secrets you type are held in server memory only for the duration of a run and +are passed to the child process through redirected standard input. They are +never placed on a command line, written to a log, stored in browser storage, or +included in a saved configuration. Loading a configuration clears the secret +field. + +## Testing a Connection + +**Test connection** runs a single bounded probe using the exact settings the +workload will use — same engine, encryption, trust, timeouts, application name, +and authentication. It does not create a history entry and does not affect a +completed run's results. + +**Run workload** performs the same bounded probe before opening Monitor or +starting the workload. If the server, database, authentication, or connection +options are invalid, Studio remains on Configure and shows the specific +connection error. This prevents a misspelled database from creating a failed +run that is only diagnosed later in Results. + +On success Studio reports the live server details: + +```text +Connected in 71 ms - SQL Server 17.0.4085.5 · Enterprise Developer Edition (64-bit) · database tempdb · driver 18.06.0001 +``` + +On failure it reports the driver's own error text, which is usually specific +enough to identify the cause — a bad password, an unreachable port, or a +certificate that failed validation. + +The test is bounded by your login timeout plus 20 seconds, and cannot run while +a workload is running. + +## Step 2 - Workload + +Choose one of four modes. The default is **Workload**. + +### Query + +Runs a single ad-hoc statement or batch from the text area. + +| Control | Flag | Default | +| --- | --- | --- | +| SQL query | `-Q` | `SELECT @@VERSION;` | +| Connections | `-n` | 10 | +| Iterations per connection | `-r` | 100 | + +Total executions is connections times iterations, shown live as you type. + +### SQL file + +Runs a `.sql` script. Browse or drop a file; the maximum size is 1 MB. + +Studio counts `GO`-separated batches in the file and multiplies them into the +total execution count. The file is staged into a private temporary directory for +the run and deleted afterward — the browser never sends a path, only content. + +| Control | Flag | Default | +| --- | --- | --- | +| SQL script | `-i` | *(required)* | +| Connections | `-n` | 10 | +| Iterations per connection | `-r` | 100 | + +### Workload + +Runs a mixed workload built from multiple scripts, each with independent +settings. Studio generates the workload JSON on the server and passes it with +`-workload`. + +| Per-group setting | Range | +| --- | --- | +| Connections | 1 to 10,000 | +| Iterations per connection | 1 or more | +| Think time | 0 to 86,400,000 ms | + +Limits: 1 to 20 groups, each script 1 MB or smaller, 10 MB combined. + +Mixed workload runs on either engine. + +**Import JSON** loads an existing sqlsim workload definition — the same file +format `sqlsim -workload` accepts — and converts its groups into Studio rows. +Groups defining inline `queries` are imported with their SQL, connection count, +iteration count, and think time. + +Two things to know about importing: + +- **`//` and `/* */` comments are tolerated.** The sqlsim workload parser accepts + them and the shipped examples use them, so Studio strips comments before + parsing rather than rejecting the file. +- **Groups that reference an external `file` are skipped.** The browser cannot + read a path from inside a JSON document. Studio reports how many groups were + skipped; add those scripts with **Add SQL script**, or convert the workload + first with `examples/convert-workload-for-studio.ps1`, which inlines each + referenced file as `queries`. + +### Replay + +Replays a converted sqlsim XEvent capture. Studio does not accept raw `.xel` +files: convert the capture with sqlsim's `replay\convert-xel.ps1` first. The +resulting `.xml` file must be 100 MB or smaller. + +To try Replay without capturing anything, load +`examples/any-database/replay/catalog-replay.xml`, which runs against any +database, or `examples/adventureworkslt/replay/portable-replay.xml` against +AdventureWorksLT. Both are genuine captures of three concurrent sessions. + +| Mode | Behavior | Connections | +| --- | --- | --- | +| **Session order (fast)** | One worker per captured session; runs each session as fast as possible while preserving its event order | Determined by the capture | +| **Load stress** | Recognized events flattened and distributed for maximum load; session boundaries are not preserved | Set with `-n` | + +**Replay passes** maps to `-r`. Stress connections is only enabled — and `-n` +only emitted — in stress mode. Selecting Replay defaults telemetry to **Final +results only** because the canonical final JSON contains the original capture +aggregates, Replay outcomes, and per-query comparison inputs. You can select +**Live progress** afterward when execution monitoring is more important than +the original-versus-Replay comparison. + +When a file is selected, Studio verifies the XML shape and shows captured, +recognized, and skipped event counts plus the captured SPID and database +context. The bounded capture preview lists SQL text, event type, captured SPID, +database, mode-specific inclusion decision, and original duration when it was +captured. Studio parses the complete file and computes the summary from every +event, but renders at most the first 100 preview rows. When more events exist, +the preview reports how many additional events are not displayed. + +This Studio release supports Replay files containing zero or one captured +database. Choose the destination server and database in Configure. When no +`database_name` action was captured, Replay runs in that selected database. +When one database was captured, Studio redirects that captured context to the +selected database before staging the private Replay XML. This allows a trace +captured from one database to run against a differently named test copy without +editing the converted file. + +Studio rejects a Replay file containing more than one distinct captured +database during preflight. Source-to-target mapping for multi-database captures +is deferred to a future release. + +Studio validates connectivity to the selected target, not schema or data +equivalence. The user must ensure the target has synchronized schema and data +before interpreting the performance comparison. Server resources, +configuration, statistics, indexes, cache state, concurrency, and Query Store +activity can still make results differ. + +Replay requires the `sqlsim` engine. It reproduces supported statements and +their order within captured sessions, not the original application's complete +runtime behavior. Event timestamps determine ordering but do not reproduce +timing gaps. Transactions, think time, connection state, and session-level +`SET` options are not captured or restored. + +Replay XML can contain SQL text, object names, parameter values, and literal +customer data. Review it before loading, saving in a Studio configuration, or +sharing it. + +Enable **Collect per-query performance** to see the replayed SQL and compare it +with original XEvent metrics. Runtime query statistics show a bounded list of +SQL Server SPIDs for each query in Query, SQL file, Workload, and Replay runs. +Results also show: + +- original and Replay outcome counts; +- original and Replay execution counts; +- original and Replay average elapsed time; +- elapsed-time and logical-read deltas; +- Replay failures; and +- the full Runtime query statistics table with SPIDs, CPU, and I/O details. + +The comparison is not limited to the 100-row preview. It aggregates the entire +capture into one row per unique exact SQL text. Repeated events contribute to +that row's execution and outcome counts and to its original metric averages. +Replay query statistics are aggregated by the same exact SQL text before the +two sides are matched; text variants remain separate rows. Original duration is +converted from XEvent microseconds to milliseconds; XEvent CPU time is already +milliseconds. Missing capture fields are shown as unavailable rather than +treated as zero. Load stress is labelled as a transformed workload because it +flattens sessions and can multiply execution counts. + +Diagnostics enable `SET STATISTICS TIME/IO` and add overhead. Disable them when +measuring maximum Replay throughput. Deltas are descriptive: environment, +cache state, concurrency, and collection overhead can all affect the result. + +## Step 3 - Execution + +### What to use when + +Client telemetry controls what Studio receives and displays while the workload +runs. Server statistics control how much per-query diagnostic work is collected. +Choose them independently based on the goal: + +| Goal | Client telemetry | Server statistics | +| --- | --- | --- | +| Watch throughput and execution progress | **Live progress** | **None** | +| Diagnose individual slow or expensive queries while the run is active | **Live progress** | **Runtime messages** | +| Measure maximum throughput with minimum collection overhead | **Final results only** | **None** | +| Compare two clean benchmark runs | **Final results only** | **None** | +| Analyze aggregate server-side query performance on a quiet test database | **Final results only** | **Query Store** | +| See returned rows or troubleshoot query output | **Console output** | **None** | + +Simple rules: + +- Start with **Live progress + None** while developing a workload. +- Add **Runtime messages** when you need per-query elapsed time, CPU, reads, + execution counts, and failures. +- Switch to **Final results only + None** for serious throughput measurements. +- Use **Query Store** only on a quiet test database; its aggregate deltas can + include matching work from other sessions. +- Use **Console output** for correctness and troubleshooting, not benchmarking. +- Keep telemetry and statistics settings identical when comparing runs. + +### Client telemetry + +This is the most consequential execution choice. It determines what Studio can +show you and what it costs to collect. + +| Mode | Flags | Monitor view | Results | +| --- | --- | --- | --- | +| **Live progress** | `-stream-json -json -o -q` | Throughput chart, counters, event stream, and live per-query statistics when runtime statistics are enabled | Full canonical metrics after completion | +| **Final results only** | `-json -o -q` | Process state and elapsed time only | Full metrics | +| **Console output** | *(neither)* | Process state and elapsed time only | Result rows, no canonical metrics | + +Choose **Live progress** to watch a run. Choose **Final results only** for +maximum throughput when client-side streaming overhead would distort the +measurement. Choose **Console output** when you want to see the rows a query +actually returned. + +For both engines, Live progress keeps NDJSON events on stdout while `-json -o` +writes the canonical final result to Studio's private run directory. Exports, +run history, and supported comparisons therefore remain available after a live +run. + +**Suppress result rows** (`-q`) is forced on and locked for Live progress and +Final results, because structured JSON telemetry requires it. In Console mode it +becomes editable; leave it off to display rows from the first execution. + +Console output is displayed up to a 256 KiB limit, after which it is truncated +with a notice. Console runs do not produce the canonical metrics required for +A/B comparison. + +### Execution toggles + +| Toggle | Flag | Notes | +| --- | --- | --- | +| Prepared statements | `-p` | Prepare once per connection. Accepted but ignored by `sqlpysim`. | +| Reconnect each iteration | `-reconnect` | Open a new connection per cycle | +| Connection pooling | `-usepool` | Requires reconnect. Supported by both engines. | +| Stop on first error | `-stoponerror` | Cancels all active workers | + +Connection pooling stays disabled until Reconnect each iteration is enabled, +because pooling only has meaning when connections are actually recycled. + +### Query statistics + +| Source | Flag | Notes | +| --- | --- | --- | +| **None** | *(none)* | Default. Live monitoring is still available. | +| **Runtime messages** | `-querystats` | Per-execution server CPU and I/O via `SET STATISTICS TIME/IO`. Requires `sqlsim`. | +| **Query Store** | *(collected by Studio)* | Before/after aggregate deltas | + +Query Store collection is performed by Studio itself using two read-only +snapshots taken around the run. It requires Query Store to be in read-write +state and the performance-state permission on the target database. Because the +deltas are aggregates, they can include matching queries executed by other +sessions during the run — Studio warns about this in the log. +When Query Store is selected, the Run preflight verifies those requirements and +keeps the user on Configure with the database error if validation fails. + +### Query timeout + +Maps to `-t`. Default 30 seconds; 0 to 86,400. Zero waits indefinitely. + +## Command Preview + +The bar above **Run workload** shows the exact command Studio will execute, +updating as you change settings: + +```text +sqlsim -S localhost -d tempdb -E -Q "SELECT @@VERSION;" -n 10 -r 100 -l 15 -app sqlsimstudio -N m -C -t 30 -stream-json -json -o studio-results.json -q +``` + +Private staging paths appear as `` and secrets never appear at +all. The preview is a reliable way to learn the command-line equivalent of a +Studio configuration, and to confirm a setting took effect before committing to +a long run. + +## Monitoring a Run + +When a run starts, Studio switches to the Monitor view. + +With **Live progress** telemetry you get: + +- **Live throughput** — executions per second over a rolling 20-second window +- **Executions**, **Connections**, **Errors**, and **Failed connections** counters +- **Workload progress** — aggregate percentage complete +- **Live query statistics** — shown when **Collect per-query performance** uses + runtime messages. Studio reads the engine's once-per-second query-statistics + snapshot and shows totals, average elapsed time split into server and client + time, average server CPU, average logical reads, execution share, and the + same per-query table used in Results. Charts show up to 10 queries with the + most total elapsed time; the table lists every query. +- **Event stream** — structured events received from the engine + +Query Store statistics are collected around the run, so they appear in Results +after completion rather than in the Monitor view. + +With Final results or Console telemetry, Studio tracks process state and elapsed +time only, and explains that in place of the chart. This is not a failure; it is +the cost of not streaming. + +**Stop run** cancels the workload and terminates the process tree. A stopped run +is recorded as stopped rather than completed. + +## Results + +The Results view summarizes the completed run: + +- **Throughput**, **Total duration**, **Executions**, **Query time**, + **Connections**, and **Errors** +- **Execution summary** — client-observed time split across query execution, + connection, and other +- **Run configuration** — workload shape, connection count, statistics source, + driver, SQL Server version and edition, and engine, for reproducibility. + Live progress runs populate driver and server details after the first + successful connection. +- **Console output** — shown for console-mode runs +- **Query statistics** — shown when runtime or Query Store statistics were + collected. Runtime statistics include the same totals and charts as Monitor, + followed by the full per-query table. If you stop a Live progress run, Results + uses the last query-statistics snapshot and labels it as partial. + +### Exporting results + +**Export JSON** downloads the run's canonical results file — the same structure +`sqlsim -json` produces, and the artifact to keep for automation, archiving, or +regression tracking. Studio runs final-results workloads with `-json`, so the +exported file includes the server version and edition, ODBC driver version, +configuration, and timing totals. It omits the per-thread, per-iteration detail +that `-v` adds, which grows with run length. + +Export requires a completed **Final results only** run. Console and live-progress +runs do not produce the canonical structure. + +### Generating an HTML report + +Studio does not render HTML reports itself. Export the results JSON, then run the +reporting script from the `sqlsim` folder of the sqlsimtools package: + +```powershell +# from the sqlsimtools folder +.\sqlsim\examples\reports\execution-report.ps1 -JsonFile .\sqlsim-results-20260925-141530.json +``` + +The script writes `execution-report.html` and opens it in your browser. + +The reporting scripts belong to sqlsim rather than Studio because they work on +any sqlsim results file, whether it came from Studio or the command line. +Keeping a single generator also means the CLI and Studio produce identical +reports rather than two implementations that drift apart. + +## Comparing Runs + +The Compare view checks whether a change improved or regressed performance. It +compares a baseline (A) with a candidate (B). + +### Two ways to compare + +| Source | Use it when | How long it is available | +| --- | --- | --- | +| **Runs from this Studio session** | You run a workload, make a change, and run it again | Until Studio exits; up to 50 completed runs | +| **Saved JSON results** | You want to keep results, compare across sessions, or compare command-line results | Import with **Import JSON** whenever needed | + +You can compare two session runs, two saved results, or one of each. + +### Compare runs from this session + +1. In **Configure**, choose the workload and settings. +2. Click **Run workload**. When it completes, Studio adds it to Compare. +3. Make the change you want to test outside Studio, such as adding an index or + changing a server setting. +4. Run the same Studio configuration again. +5. Open **Compare**, select the earlier run as **A · Baseline**, and select the + later run as **B · Candidate**. + +Studio keeps completed **Final results only** and **Live progress** runs. +Console output, stopped, failed, and connection-test runs are not available, +because they do not produce a complete final result. + +Use the same telemetry setting for A and B. **Live progress** streams updates +while the workload runs, so it adds client-side work. Studio refuses to compare +a Live progress run with a Final results run. For the most accurate measurement, +use Final results only for both runs. + +### Save and compare results later + +Use **Export JSON** on Results to keep a run after Studio exits. Later, use +**Import JSON** in Compare to load it as Baseline or Candidate. You can also +import a final result written by `sqlsim` or `sqlpysim` with `-json -o `. + +### What can change between A and B + +| Difference | Compare behavior | +| --- | --- | +| Index, server setting, statistics, hardware, or other change outside Studio | Allowed | +| SQL Server version or edition, ODBC driver, or engine version | Allowed and flagged as informational | +| Query or workload SQL | Refused | +| Server or database | Refused | +| Connections, iterations, or execution count | Refused | +| sqlsim or sqlpysim engine | Refused | +| Query statistics setting | Refused | +| Live progress or Final results telemetry | Refused | +| Connection options such as reconnect, pooling, encryption, or timeouts | Refused | + +When Compare refuses a pair, it names the differing setting and does not show +performance deltas. + +### Reading the comparison + +Select a baseline (A) and candidate (B). Studio reports percentage deltas for +throughput, total duration, average execution time, average connection time, and +errors, with an explicit verdict of how many metrics improved, stayed the same, +or regressed. Changes within ±2% count as unchanged. + +Studio and `comparison-report.ps1` use the same definitions: + +- **Throughput** — executions divided by `execution_elapsed_seconds`, or total + duration when the result does not record execution elapsed time +- **Total duration** — wall-clock time for the whole run, including connections +- **Executions** — total batches, or replayed events for Replay +- **Average execution** — total query execution time divided by executions +- **Average connection** — the engine's average connection time. It counts + toward the verdict only when both runs use `-reconnect`; otherwise it is + one-time setup cost and is shown as **not in verdict**. + +**Per-query comparison** appears when both results include per-query statistics +from `-querystats`. Queries are matched by SQL text with whitespace normalized, +and each row shows executions, average elapsed time, average CPU, average +logical reads, and failures for A and B. Queries found in only one run are +labeled **Only in A** or **Only in B**. + +**Configuration comparison** is the guardrail that matters. It lists the +target, workload checksum, load shape, statistics, telemetry, engine, driver, +and SQL Server details for A and B. A throughput difference between two runs +with different workloads or load shapes is not a result; this panel is what +stops you from reporting one. sqlsim and sqlpysim record SQL Server version and +edition in every JSON result. + +### Importing saved results + +Use **Import JSON** above Baseline or Candidate to load either: + +- A final result written by `sqlsim` or `sqlpysim` with `-json -o `, or by + Studio's **Export JSON** button. +- A Studio **Export comparison** bundle. Studio loads its baseline and candidate + together. + +Imported files are parsed in the browser and are not uploaded to the Studio +server. They remain available until the page is reloaded or Studio exits; at +most 20 imported results are kept. + +The sqlsimtools package includes a sample pair in `sqlsim/examples/results/`: +`index-baseline.json` and `index-candidate.json`. Import them as Baseline and +Candidate to see a comparable before-and-after index change. + +When either side is imported, Studio compares the configuration recorded in the +result files: engine and mode, target, workload batches or Replay capture, load +shape, statistics setting, telemetry, and execution options such as +authentication, application name, encryption, timeouts, reconnect, pooling, and +prepared statements. File paths and verbose output are ignored. A plain result +file records runtime query statistics but not Studio Query Store collection, so +Studio treats Query Store as unavailable unless the file came from a Studio +comparison bundle. + +Failed runs, connection tests, duration-mode results, live-progress streams, and +files that are not canonical final results are rejected. + +Run history is bounded and held in memory for the current Studio session only. +It is discarded when Studio exits. + +### Exporting a comparison + +**Export comparison** downloads both runs and the computed analysis as a single +JSON file: each run's full canonical result, the percentage deltas, and the +configuration-match verdict. + +Render it as an HTML report with the sqlsim comparison script: + +```powershell +# from the sqlsimtools folder +.\sqlsim\examples\reports\comparison-report.ps1 -ComparisonFile .\sqlsim-comparison-20260925T141530.json +``` + +The same script also compares two ordinary result files directly, which does not +require Studio at all: + +```powershell +.\sqlsim\examples\reports\comparison-report.ps1 -BaselineFile before.json -CandidateFile after.json +``` + +Use this script when you want an HTML report. To review saved results +interactively, import them into Compare instead. + +The report repeats Studio's configuration guardrail and refuses to declare a +verdict when the two runs used different targets, engines, workloads, load +shapes, query-statistics settings, or execution options. Use +`-Threshold` to set the percentage treated as noise; it defaults to 2, which is +tight for short runs where normal variance is larger than the effect you are +measuring. + +## Saving and Loading Configurations + +**Save configuration** downloads the current mode and its settings as a +versioned JSON file. SQL script and replay content are embedded so the +configuration can be restored without reselecting files. + +**Passwords and tokens are never included.** Loading any configuration clears +the current secret field, so you re-enter the credential deliberately. + +Treat saved configurations as sensitive when their query or script text contains +environment-specific information. + +See [CONFIGURATION.md](CONFIGURATION.md) for the version 1 JSON contract, +mode-specific source objects, validation limits, and examples. + +## Execution Log + +**View log** opens a drawer with sanitized, session-only log entries, filterable +by All, Errors, or Warnings. Credentials and tokens are never recorded. +Connection strings are sanitized before any entry is written. + +Log entries are discarded when Studio closes. + +## App Settings + +The gear icon opens preferences. **Theme** offers Light, Dark, Use system +setting, and six color themes. Blue, Red & Blue, Green & Black, and Green & Gold +color the whole screen; Blue matches the Tomorrow Night Blue theme in VS Code. +Royal Blue and Green keep Light's white panels with a colored navigation rail +and accents; Green uses Microsoft Fabric's teal green. It does not change any +workload setting, and saved configuration files never include it. + +Clicking OK saves the theme for your user account, so it applies every time +Studio starts, in any browser. Studio keeps it in `settings.json` under +`%LOCALAPPDATA%\sqlsimstudio` on Windows, `~/.local/share/sqlsimstudio` on +Linux, and `~/Library/Application Support/sqlsimstudio` on macOS. The file +holds only the theme name, never credentials. Delete it to return to Use system +setting. If the file is missing or unreadable, Studio starts normally with the +theme last used in that browser. Set `SQLSIMSTUDIO_SETTINGS_DIR` to keep the +file elsewhere; the test scripts do this so they never change your preference. + +## Choosing Between sqlsim and sqlpysim + +Studio can drive either engine. `sqlsim` is the default and the more capable. + +| Capability | sqlsim | sqlpysim | +| --- | --- | --- | +| Query mode | Yes | Yes | +| SQL file mode | Yes | Yes | +| Mixed workload | Yes | Yes | +| Replay | Yes | No — deliberately deferred from sqlpysim v1.0 | +| Live progress telemetry | Yes | Yes | +| Final results / console | Yes | Yes | +| Runtime query statistics | Yes | Yes | +| Query Store statistics | Yes | Yes | +| Prepared statements | Yes | Accepted, ignored | +| Connection pooling | Yes | Yes, with reconnect mode | + +Studio enforces these differences in the interface: selecting `sqlpysim` +disables the capabilities it does not support and switches away from an +incompatible mode rather than failing at run time. + +Use `sqlpysim` when you want to measure `mssql-python` driver behavior or +compare it against native ODBC. Use `sqlsim` for everything else, particularly +for XEvent replay and maximum-throughput load testing where client overhead +matters. + +`sqlpysim` requires Python and its dependencies to be installed; the package +ships the source, not a runtime. + +## Security Model + +Studio treats the local browser as untrusted. The protections are deliberate and +worth understanding: + +- **Loopback only.** Kestrel binds to `127.0.0.1` on a random port. Studio is + not reachable from the network. +- **One-time bootstrap.** A single-use 256-bit token establishes the session. +- **Session cookie.** `HttpOnly` and `SameSite=Strict`, so script cannot read it + and cross-site requests cannot use it. +- **Host and Origin validation.** Unexpected `Host` headers are rejected, and + unsafe methods require a matching `Origin`. +- **No CORS, no request logging.** +- **Unauthenticated requests receive 404,** including static assets, so the + application's existence is not confirmed to an unauthenticated caller. +- **Secrets over standard input.** Never on a command line, in a URL, in browser + storage, or in a saved configuration. +- **Private staging.** Script and replay content is written to a per-run private + directory and deleted when the run completes. + +The browser never connects to SQL Server directly. All database access happens +in the Studio process or its child workload processes. + +## Known Limitations + +Studio ships only controls that work. Unimplemented features are absent from the +interface rather than present and greyed out, so a visible button always does +something. + +One option disables itself based on where Studio runs because the capability +genuinely is not available: + +| Option | Unavailable when | +| --- | --- | +| Microsoft Entra interactive | Studio is running on Linux or macOS | + +Planned for a future preview revision, currently absent from the interface: + +| Area | Feature | +| --- | --- | +| Monitor | Copy events to the clipboard | +| Results | Run again, open a completed run's configuration | +| Execution log | Copy, export, and clear the log display | + +The execution log itself works — severity filtering, entry counts, and entries +are all live. Only the clipboard, export, and clear actions are outstanding. + +**Not limitations.** Several controls start disabled and enable themselves when +they become meaningful. These are working as intended: + +| Control | Enables when | +| --- | --- | +| Stress connections | Replay mode is set to Stress | +| Connection pooling | Reconnect each iteration is enabled | +| Suppress result rows | Telemetry is set to Console output | +| Stop run | A workload is running | +| Baseline / Candidate | A final-result run exists in this session or a result file is imported | + +**Run history is session-scoped.** It is held in memory, bounded, and discarded +when Studio exits. To compare runs across sessions, use **Export JSON** on each +run, then use **Import JSON** in Compare. + +## Troubleshooting + +**The browser did not open.** +Studio has no console window to read the address from, so restart it: the +bootstrap token is single-use and a fresh one is issued each time. To capture +the address instead, start Studio with +`--no-open --bootstrap-file ` and open the URL written to that file, or +launch it from a terminal, where it still prints `SQLSIM_STUDIO_URL`. + +**Studio exited on its own.** +It should not. Studio runs until you shut it down from the interface or the +process is killed, and it does not watch the browser. If it exits while you +are still using it, that is a defect worth reporting: capture what you were +doing and whether a workload was running. + +**A page says Studio is no longer running.** +That tab belongs to an instance that has exited. If Studio is still running, +reopen the interface from the URL in `%TEMP%\sqlsimstudio-session-.url`, +which always holds an unused token. If it has gone, start Studio again and use +the tab it opens. + +**"sqlsim is not installed where Studio can find it."** +The engine is missing from the extracted folder. Re-extract the full +sqlsimtools archive; Studio looks for `sqlsim\x64\sqlsim.exe` in the +sqlsimtools folder, one level above `sqlsimstudio.exe`. + +**"sqlpysim is not installed where Studio can find it."** +`sqlpysim/sqlpysim.py` is missing from the extracted folder. Re-extract the full +archive. + +**The engine list says Python not found or mssql-python not installed.** +Follow [Enabling sqlpysim](#enabling-sqlpysim), then refresh Studio. If Python +is installed elsewhere, set `SQLSIM_STUDIO_PYTHON_PATH` to that Python +executable before starting Studio. + +**Connection fails with a certificate error.** +Either enable **Trust server certificate**, or set **Certificate hostname** to +the name on the certificate. Use Test connection to iterate quickly. + +**Entra token authentication worked earlier and now fails.** +Access tokens expire in about an hour. Acquire a new one. + +**Test connection reports success but a workload fails.** +The connection is fine; the problem is in the workload. Check the execution log, +and consider running once in Console output mode to see what the server actually +returned. + +**The Monitor view shows no chart.** +Live progress telemetry is required for charting. Final results and Console +modes intentionally track only process state and elapsed time. + +**Compare refuses two runs.** +Session runs must be completed Final results only or Live progress runs, and +both sides must use the same telemetry. Imported files must be canonical final +results with a fixed execution count. Check the configuration comparison panel +for an engine, workload, target, load-shape, statistics, telemetry, or +execution-option mismatch. + +**A run is slower than the same command on the command line.** +Live progress telemetry adds client-side streaming work. Use Final results only +for measurement runs. + +## Getting Help + +- Configuration file contract: [CONFIGURATION.md](CONFIGURATION.md) +- `sqlsim` command-line manual: https://github.com/microsoft/sqlsimtools/blob/main/sqlsim/sqlsim.md +- Studio architecture and development notes: https://github.com/microsoft/sqlsimtools/blob/main/sqlsimstudio/README.md +- Issues and discussions: https://github.com/microsoft/sqlsimtools diff --git a/sqlsimtools.code-workspace b/sqlsimtools.code-workspace new file mode 100644 index 0000000..ba85587 --- /dev/null +++ b/sqlsimtools.code-workspace @@ -0,0 +1,10 @@ +{ + "folders": [ + { + "path": "." + } + ], + "settings": { + "powershell.cwd": "sqlsimtools" + } +} \ No newline at end of file
